Curl error 7 failed to connect to downloads wordpress org port 443 connection refused

Error: [] cURL error 7:

I installed WP in a VM at home to perform some tests.
Everything was working well, I can access to website from internet, etc…
But when I go to “Tools > Site Health”, I have 3 Critical issues. All of them related to a “cURL error 7”, but without any details related to which error.

The REST API encountered an error
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:

Could not reach WordPress.org
Communicating with the WordPress servers is used to check for new versions, and to both install and update WordPress core, themes or plugins.

Error Your site is unable to reach WordPress.org at 198.143.164.251, and returned the error: cURL error 7:

Your site could not complete a loopback request
Loopback requests are used to run scheduled events, and are also used by the built-in editors for themes and plugins to verify code stability.

The loopback request to your site failed, this means features relying on them are not currently working as expected.
Error: [] cURL error 7:

When I connect to Unix hosting WP, I’m able to perform a cURL to WordPress, and reach internet.
I can’t find what is going on and how to fix it, since there is no error details, neither in WP logs.

cURL error 7: Failed to connect to jetpack.wordpress.com port 443: Connection re

I suddenly got error “cURL error 7: Failed to connect to jetpack.wordpress.com port 443: Connection refused”

I have already:
1.tried to deactivate/delete/install/activate
2.contacted hosting provider – confirmed that SSL certificate is all right
3.tried https://jptools.wordpress.com/debug/ and got “Something has gone wrong with our servers, and we’ve just been notified of the problem.”

I kindly ask for help here.
Thanks!

The page I need help with: [log in to see the link]

I have found http_request_failed: cURL error 28: Connection timed out after 10000 milliseconds error in our system.

Generally, seeing the timeout error like that and not being able to connect at all points to something still on your server blocking Jetpack.

In this case, I would recommend reaching out to your web host to first make sure that Jetpack is not getting blocked or limited or is prevented from accessing your xmlrpc.php file: https://YOURSITENAME.hr/xmlrpc.php?for=jetpack. This file is used by Jetpack and other plugins and apps to connect to your site. For the best results, you could also have them whitelist the Jetpack IP ranges noted on this page:

If you’re unsure about this, you may contact your hosting provider; they should be able to help you with this. Please note that these IP addresses could change (or more could be added) at any time. For that reason, we recommend your host uses the machine-readable versions of these IP ranges in JSON or plain text format to automate configuration changes on their systems.

Let me know how it goes!

As a side note: do you have any security plugins installed?

It has been more than one week since we have heard from you, so I’m marking this topic as resolved. But If you have any further questions or need some more help, you’re welcome to reply here or open another thread.

cURL error 7: Failed to connect to noc1.wordfence.com

Wordfence is not able to download new rules or run scans. In diagnostics, I see this:

I checked with the host and they said they are not blocking anything related to Wordfence and suggested the issue was on the Wordfence end.

Hi @ncj, thanks for getting in touch!

A cURL error 7 often indicates the communication to our servers and back to your site is unable to happen at all. This error number can be solved from the hosts’ end, so it might be worth checking in with their support channels to see whether they’re able to communicate with noc1.wordfence.com or whether this is blocked at their end.

However, I’m more than happy to check a site diagnostic report to see if there are any blocks in place or whether I can communicate TO your server from outside. That might help narrow down the stage at which the communication error occurs.

Can you send the diagnostic report to wftest @ wordfence . com? You can find the link to do so at the top of the Wordfence > Tools > Diagnostics page. Then click on “Send Report by Email”. Please add your forum username where indicated and respond here after you have sent it.

Thanks, I had already checked with the hosting company (Bluehost) and they told me it wasn’t blocked on their end.

I sent the diagnostic report.

Hi, following up to see if you had received the diagnostic report and if you had any suggestions on how to resolve this issue.

Hi @ncj, thanks for sending your diagnostic report over.

Usually the communication issues we see are fairly descriptive or show a blocking page of some kind to indicate the connection was unable to make it through due to a firewall rule or load balancer at the server. In this case, the cURL error 7 is just a “Connection Refused” which is what I’d suspected originally.

I have discovered that your server IP has however been blocklisted by Wordfence in the past, possibly due to being on a shared server with a site that has previously been found to be malicious. It is not currently blocked, so connectivity to the noc1 servers in your Diagnostics page should be restored. Can you let me know if this is the case?

Error: cURL error 7: Failed connect to mysite.com:443; Connection refuse

Hey Guys
I recently migrated my site from google cloud to AWS. Everything went fine except I am having this error that I think is affecting my cron jobs. I have a site health plugin and these are the two errors that I am getting from two areas
1. The REST API encountered an error
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 connect to mysite.com:443; Connection refused

2. Your site could not complete a loopback request
Loopback requests are used to run scheduled events and are also used by the built-in editors for themes and plugins to verify code stability.
The loopback request to your site failed, this means features relying on them are not currently working as expected.
Error encountered: (0) cURL error 7: Failed connect to mysite.com:443; Connection refused
3. A scheduled event has failed
The scheduled event, add_every_three_minutes, failed to run. Your site still works, but this may indicate that scheduling posts or automated updates may not work as intended.

The event in 3 above is a custom plugin that runs a cron job that is currently not executing.
This is what I’ve done so far
1. aws came with PHP 8 so I downgraded to php7.3 because it seems all my plugins use that as the maximum compatible version. No Help)
2. Disable Selinux (read that online. and no help)
3. Updated curl (no help)
4. made sure all the ports (both HTTP 80 and HTTP 443 are open incoming and outgoing. (no help)
5. Added both hostnames, localhost, and IP to hosts file (no help)
6. tried to add an alternate cron to the function file but this actually broke my site
with HTTP 500 error.
That’s where am stuck and I don’t know what else to try, so any help would be appreciated guys thanks

curl: (7) Failed to connect to getcomposer.org port 443: Connection refused

I am trying to download composer on Ubuntu Desktop(20.04 LTS) using curl -sS https://getcomposer.org/installer -o composer-setup.php and I am encountering

curl: (7) Failed to connect to getcomposer.org port 443: Connection refused

Note: I am even unable to access the official website. It says getcomposer.org refused to connect.

Troubleshooting steps which I performed:

1. ping getcomposer.org gives me

2. curl -sS https://www.google.com gives me HTML output.

<!doctype html><html itemscope="" itemtype="http://schema.org/WebPage" lang="en-IN"><head><meta content="

3. echo ipv4 >> ~/.curlrc to add a flag in curl config file(~/.curlrc) to use IPv4 always instead IPV6. And then I tried curl --ipv4 -sS "https://getcomposer.org/installer" -o composer-setup.php. Still the same error.

4. lsof -i -P -n gives

Questions:

1. Why getcomposer.org/ shows refusing to connect through — Network issue?

2. curl: (7) Failed to connect to getcomposer.org port 443: Connection refused on curl -sS https://getcomposer.org/installer -o composer-setup.php. Not sure what could be causing this?
