For a couple of days I was totally blocked on this. I’m very very new to networking/vms but was keen to try set it up myself instead of paying a hosting company to do it for me.
Context
I’m rebuilding the server side for an app that uses php routines to return various bits of data from internal sources as well as external APIs for a map based app. I have started an Oracle VM instance and have installed/set up Apache and php. All running totally fine, until one of my php routines tries to execute a cURL. I start implementing error logging to find that I don’t even get a message — just ‘7’, despite implementation being very similar to the above. My php routine accessing an internal file for data was running successfully so I was fairly sure it wasn’t an Apache or php issue. I also checked my Apache error logs, nothing telling.
Solution
I nearly gave up — there’s talk on disabling SELinux above and in other articles, I tried that and it did work for my purposes, but here’s a really good article on why you shouldn’t disable SELinux https://www.electronicdesign.com/technologies/embedded-revolution/article/21807408/dont-do-it-disabling-selinux
If temporarily disabling it works and like me you don’t want to do this (but it confirms that SELinux is blocking you!), I found a neat little command that actually prints out any SELinux issues in a more readable fashion:
sealert -a /var/log/audit/audit.log
This returned the following:
found 1 alerts in /var/log/audit/audit.log
--------------------------------------------------------------------------------
SELinux is preventing php-fpm from name_connect access on the tcp_socket port 443.
Great, I now get a bit more information than just ‘7’. Reading further down, I can see it actually makes suggestions:
***** Plugin catchall_boolean (24.7 confidence) suggests ******************
If you want to allow httpd to can network connect
Then you must tell SELinux about this by enabling the 'httpd_can_network_connect' boolean.
Do
setsebool -P httpd_can_network_connect 1
This has been mentioned further above but now I have a bit more context and an explanation as to what it does. I run the command, and I’m in business. Furthermore, my SELinux is still set to enforcing, meaning my machine is more secure.
There are many other suggestions logged out, if you’re blocked it might be worth logging out/checking out /var/log/audit/audit.log.
Are you frustrated with cURL error 7 failed to connect to port 443?
This error is common when using PayPal or Facebook login scripts on the website. This mainly occurs when the server firewall blocks the curl request.
At Bobcares, we often receive requests to fix this error as part of our Server Management Services.
Today, let’s discuss the error in detail and see how our Support Engineers fix it for our customers.
What is cURL error 7?
Have any idea about when does the curl error occur?
Curl error 7 mainly occurs when the TCP connection to a given host/port fails. It ends up in an error message.
PHP Fatal error: Uncaught exception 'Exception' with message 'cURL error: [7] Failed to connect to xxx.paypal.com port 443: Connection refused'Let’s discuss the details of the exact scenario of the error. Recently, one of our WordPress customers approached us with a request stating:
I have installed a theme on my site, however, the theme won’t validate. I’ve installed a Query Monitor and saw that I’m receiving a cURL 7 error. Could you please help me resolve this issue?
On checking the error, our Support engineers ensured that no firewall was blocking outbound connection in this server. Also, we found port 443 opened in TCP In/Out and UDP Out for both IPv4 and IPv6.
How we fix cURL error 7 failed to connect to port 443?
So far we have seen the error in depth. Now, let’s check how our Support Engineers fix it efficiently.
Our Support Engineers tried to issue a telnet session to the host server and found some connection errors.
Upon checking, we found that the customer’s IP has been blocked in the WordPress theme update server. And, that is this error has occurred.
We asked the customer to contact them to whitelist the IP in their firewall. This resolved the error and the theme activation worked fine.
[Need more help to solve this error?- We’re available 24/7 to help you.]
Conclusion
In short, cURL error 7 failed to connect to port 443 mainly occurs when the firewall blocks the curl request. Today, we have discussed this error in detail and saw how our Support Engineers fix it for our customers.

Я отправляю код элемента веб-службе в формате xml с помощью cUrl (php). Я получаю правильный ответ в localhost, но когда это делает сервер, он показывает
Я отправляю код товара в таблицу и извлекаю детали из него. Я пробовал использовать как версии php 4+, так и php5 +, ничего не получается. Любое решение.
Код ошибки CURL 7 (CURLE_COULDNT_CONNECT)
очень явный … это означает Failed to connect() to host or proxy.
Следующий код будет работать в любой системе:
$ch = curl_init("http://google.com"); // initialize curl handle curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1); $data = curl_exec($ch); print($data);
Если вы не видите страницу google, то .. your URL is wrong или у вас есть проблема с firewall или restriction .
Вызывается ошибка CURL ERROR 7 Не удалось подключиться к разрешению отказа от прав, когда по какой-либо причине запрос на завивание блокируется каким-либо брандмауэром или подобной вещью.
вы столкнетесь с этой проблемой, когда когда-либо запрос на завивание не со стандартными портами.
например, если вы зависаете с некоторым URL-адресом, который находится на порту 1234, вы столкнетесь с этой проблемой, когда URL-адрес с портом 80 даст вам результаты легко.
Чаще всего эта ошибка наблюдается в CentOS и любой другой ОС с «SElinux».
вам нужно либо отключить, либо изменить «SElinux» на разрешающий
взгляните на этот
Надеюсь это поможет
Можете ли вы ударить по этому URL браузером или скриптом PHP? Произошла ошибка: вы не можете подключиться. Поэтому сначала убедитесь, что URL доступен.
В PHP, если ваша сеть под прокси. Вы должны установить URL-адрес прокси-сервера и порт
curl_setopt($ch, CURLOPT_PROXY, "http://url.com"); //your proxy url curl_setopt($ch, CURLOPT_PROXYPORT, "80"); // your proxy port number
Это решает мою проблему
Проверьте, заблокированы ли порты 80 и 443. или введите – IP graph.facebook.com и введите его в файл etc / hosts
Эта проблема также может быть вызвана созданием зависающих вызовов на https, когда она не настроена на удаленном устройстве. Вызов HTTP может решить эту проблему в этих ситуациях, по крайней мере, до тех пор, пока вы не настроите ssl на удаленном компьютере.
В моем случае у меня было что-то вроде cURL Error (7): ... Operation Timed Out . Я использую сетевое подключение компании, над которой я работаю. Мне нужно было создать некоторые переменные среды. Следующий работал для меня:
В терминале Linux:
$ export https_proxy=yourProxy:80 $ export http_proxy=yourProxy:80
В Windows я создал (то же) переменные среды в пути Windows.
Я надеюсь, что это помогает!
С уважением!
В моем случае проблема была вызвана хостинг-провайдером, который я использовал блокирование http-пакетов, адресованных их IP-блоку, которые возникли из их IP-блока. Un-frickin-правдоподобно !!!
вы также можете получить это, если вы пытаетесь одновременно использовать один и тот же URL-адрес с несколькими HTTP-запросами. Многие запросы на завивки не смогут подключаться и поэтому возвращаются с ошибкой

You are getting the following error when you go to check your WordPress performance under site health analyze :
The REST API is one way WordPress, and other applications, communicate with the server. One example is the block editor screen, which relies on this to display, and save, your posts and pages.
The REST API request failed due to an error.
Error: cURL error 7: Failed to connect to localhost port 8080: Connection refused (http_request_failed)
You also may have errors as :
- Background updates.
- Your site could not complete loopback request
How to resolve it
The curl error is very explicit: It means “Failed to connect() to host or proxy.”
You may have a firewall on your server or your localhost computer if WordPress is on your localhost. Check if port 80 and 443 are blocked, or check your personal firewall.
Sometimes, Curl will use the post 8080 instead of the classic port 80. So you also should be sure that your server uses the port 80 on your server settings.
Also, you should look at your security plugin if you have one enabled. Try to disable it.
If this curl problem causes others problems like page & post updating, then you should follow this process:
- Create a backup of FTP files and database
- Disable all plugins
- Switch to the default theme
- Clear the cache of your plugins of your browser, your hosting, your CDN.
- Rename your .htaccess file (by .htaccess.old for example). Go to the permalinks settings page, and click on save (it will flush permalinks).
- If it doesn’t work, try to change tour permalinks from “Month and name” to “Plain”.
Hi
I’m having a similar problem “Couldn’t connect to server: parsoidserver-http-error: (curl error: 7)”
Firstly I’m new to using MediaWiki, VisualEditor and Parsoid although I’m very familiar with Linux OS over many years. I’ve installed the above on to Linux workstation running Centos 6.5 as follow:
- MediaWiki from mediawiki-1.26.2.tar
- VisualEditor from VisualEditor-REL1_26-a733545.tar
- Parsoid from https://gerrit.wikimedia.org/r/p/mediawiki/services/parsoid
This Linux workstation is known to our LAN as “carme”
URL to my wiki is http://carme/w
Path to my wiki is /var/www/html/w
After configured Localsetting.js I started the parsoid service as follows:
cd /opt/parsoid
node bin/server.js
I get the following message:
[info][master][6165] initializing 5 workers
[info][worker][6167] loading …
[info][worker][6170] loading …
[info][worker][6169] loading …
[info][worker][6172] loading …
[info][worker][6167] ready on :8000
[info][worker][6174] loading …
[info][worker][6170] ready on :8000
[info][worker][6169] ready on :8000
[info][worker][6172] ready on :8000
[info][worker][6174] ready on :8000
So it looks like parsoid service is functioning and in a Chrome browser on window pc within the same LAN if I enter:
http://carme:8000
I get the following page (between ==== ) displayed:
====
Welcome to the Parsoid web service.
See the API documentation on mediawiki.org.
There are also some convenient tools for experiments. These are not part of the public API.
- Round-trip test pages, for example: /_rt/mediawiki/Parsoid
- WikiText -> HTML DOM -> WikiText round-trip form
- WikiText -> HTML DOM form
- HTML DOM -> WikiText form
====
And if I click these links and follow the instructions it all appears to work as expected.
On my wiki I can see the default main page http://carme/w/index.php/Main_Page with both the “Edit” and “Edit source” tabs displayed. So it looks like my mediawiki is using the VisualEditor extension. If on this page I click the “Edit” tab I get a progress bar but before it completes I get an error message box displaying:
carme says:
Error loading data from server: (curl error: 7) parsoidserver-http-error: (curl error: 7). Would you like to retry.
Also if I try to create a new page by entering: http://carme/w/index.php/New_test I get a “Create” and “Create source” tab. If I click “Create” tab then I get VisualEditor interface allowing me to create my new test page. The VisualEditor appears to work as expected. However when I do to Save page I get message box saying:
Something went wrong
Parsoidserver-http-error: (curl error: 7)
I think the problem is something to do with the configuration between Mediawiki, VisualEditor and Parsoid but I can’t seem to work it out. I can provide configuration for Localsetting.php and localsettings.js if that would help.
I would be very grateful for any help that offered.

Hi,
When using cURL at a PHP script, it produces error (7) at times.
I notice this on PayPal IPN script and Facebook login scripts which both use cURL.
Here is a sample error message:
PHP Fatal error: Uncaught exception ‘Exception’ with message ‘cURL error: [7] Failed to connect to ipnpb.paypal.com port 443: Connection refused’
When I try using fsockopen for PayPal IPN, the error goes away. So, I already have a workaround. I am interested though to solve the cURL problem.
When the error hits, the only way I have to fix it, is to UPDATE WHM. When I update WHM, it is fixed. I suspect that during WHM update, something is restarted perhaps. What could this be?
Is perhaps cURL failing at some way? Perhaps tailwatchd could be helpful at such?
The frequency is random and I do not know what causes it. It can be once per day or once per week. There is no standard. I do update WHM daily anyway, to auto fix this, just in case.
However, when I read the update log, I see no reported issues. Everything seem fine.
This is not a firewall issue. I have already checked this. In general, I have checked a lot of things over… the years for this issue. I have found ways to work around it but it would be great if I could fix it at the first place.
Thank you

Thank you for your response.
I have came across one of the links. Following the other one, I found different versions for openssl on the machine:

Hi @eVdaimon
Can you run the following on your server and let me know the output?
Thanks!

Hi @eVdaimon
If you run
is there an update available? If not do you have anything excluding OpenSSL updates in /etc/yum.conf?
Code:
grep "exclude" /etc/yum.confAlso if you go to WHM>>Service Configuration>>Apache Configuration -> Global Configuration ->SSL/TLS Protocols can you tell me what protocols are enabled?
Thanks!

The default option is TLSv1.2 though but is not checked.
In a production site, I used this to check what is used:

$curl_info = curl_version();
echo $curl_info['ssl_version'];I get:

Great, I’m watching that ticket and I’ll add an update here with the analyst’s findings as soon as available.

#11
Hello,
Based on the ticket it looks like the analysts were no longer able to replicate a connection issue. Can you confirm you’re now able to connect to paypal successfully?
-
#12
The analysts were not able to replicate it, indeed. It is because the server works fine most of the time and when it does, the issue does not happen. At some point it breaks and it is not only connection to PayPal that suffers but in general, any connection to a tls host.
We will wait for a time when the problem appears again, so the analysts can check it that time.

#13
Hello,
I posted to contribute the final verdict as found by cPanel support tickets.
It seems that nscd was responsible for these errors. A possible corruption of the «hosts» cache files has been indicated as the possible source of the trouble.
This was the commands chosen to fix it.
21:44:32] [11210247] [~]$ nscd —invalidate=hosts
[21:45:20] [11210247] [~]$ /scripts/restartsrv_nscd —status
nscd (/usr/sbin/nscd) is running as nscd with PID 45264 (pidfile+/proc check method).
There is no certainty that the problem will not re-appear but still the issue needs to be flagged as solved as the source was identified and the fix above worked.
Thank you
