An error occurred this port is already used by another user

The port 1337 is already used by another application #3762

Describe the bug
The port 1337 is already used by another application.

Steps to reproduce the behavior

1. Create a project
2. npm run develop

Expected behavior
Use a port that’s not use.
Maybe in a first step we could just change the default port.

Additional context
Editable in Projectconfigenvironmentsdevelopmentserver.json

The text was updated successfully, but these errors were encountered:

You could either try to kill the opened port : sudo lsof -t -i:1337 or sudo kill $(lsof -ti:1337)
or you could start the project with a different port: npm run develop — -p 5000

Or you can close the terminal and open it again

sudo fuser -k 1337/tcp

you could start the project with a different port: npm run develop — -p 5000

@yassinebridi — Hi. I was curious if you have read somewhere that npm run develop — -p 5000 , should work?

This part of the docs, https://strapi.io/documentation/3.0.0-beta.x/guides/deployment.html#configuration, explains how to set-up Strapi on a different port (in case of conflicts or other reasons).

I am marking this issue as closed as it is not a bug with Strapi itself but the users environment.

You are welcome to change the port used by strapi in the config path you found, this is also documented in the link that @davidkartuzinski gave.

Also in the future please be sure to completely fill out the bug report including the section templated as this:

This worked out for me.

Before error (windows 10)

solution

Under:
my-projectconfigenvironmentsdevelopment

I change the port to 5000 — and the problem solved 🙂

NPM example: cd to my app folder and run

In my case (Windows 10 + wsl2) is the «RzSDKService» using the 1337 port

1. Check if port 1337 used
   Run «Command Prompt» as admin netstat -ab
2. Check which PID is using port 1337
   Run «Command Prompt» as admin netstat -ano | findstr :1337
3. Find the process using the PID found from the last step, in «Task Manager»‘s «Detail» tab by matching the PID
   In my case is the «RzSDKService»
4. Kill the PID (Strapi works after killing the PID and freeing up the port)
   Run «Command Prompt» as admin taskkill /PID

/F

It would be helpful if you could provide some background information.

It is a PXE enabled DP with WDS installed in an SCCM environment, is it right?

It looks like a port issue. The PXE-enabled distribution point and the client in Windows PE select dynamically allocated high ports for TFTP transfers. These ports are defined by Microsoft between 49152 and 65535. For more information, see Service overview and network port requirements for Windows and Trivial FTP (TFTP) Daemon.

Check firewall if you enable above ports.

Hope my answer could help you and look forward to your feedback.

strange it started to work before we find a cause.

Security / System Center Configuration Manager Current Branch / SQL

Glad to hear it works again.

However, based on the error message, the high ports used for TFTP are disabled or occupied which causes this issue. If it occurs next time, we could start our troubleshooting in this direction.

Security / System Center Configuration Manager Current Branch / SQL

Hello I have a similar error

Error creating the UDP endpoint for provider «WDSTFTP» on interface «169.254.33.162:54669». Such errors may occur if the network interface has been disabled or modified, or if the port is already in use by another application. The provider cannot receive requests on this interface.

Error information: 0x2741

This is SCCM Server with WDS Installed

We did an upgrade of the SCCM server and this error appeared and hasnt dissapeared

There is no interface on the Server with this Private IP Address

There is no DHCP service running on teh same server, which i read can be the reason for this specific error.

Does anyone know why it might be reporting this interface that doesnt exist

The error was not there before

OSD Deployment is working ok after the upgrade.

Ошибка сервера Django: порт уже используется

Перезапуск сервера Django отображает следующую ошибку:

Эта проблема возникает именно в Ubuntu, а не в других операционных системах. Как я могу освободить порт для перезагрузки сервера?

Более простое решение просто введите sudo fuser -k 8000/tcp .
Это должно убить все процессы, связанные с портом 8000.

Для пользователей osx вы можете использовать sudo lsof -t -i tcp:8000 | xargs kill -9

Он покажет что-то вроде этого.

Теперь просто закройте порт, в котором запущен Django/python, убив связанный с ним процесс.

Теперь запустите приложение Django.

Мы не используем эту команду Потому что он закрывает все вкладки… Вы должны использовать

ps -ef | grep python (показать весь процесс с id)

kill -9 11633
(11633 – это идентификатор процесса для: -/bin/python manage.py runningerver)

Это расширение на ответ Мунира. Я добавил bash script, который охватывает это для вас. Просто запустите ./scripts/runserver.sh вместо ./manage.py runserver , и он будет работать точно так же.

По умолчанию команда runserver запускает сервер разработки с внутреннего IP-адреса на порту 8000.

Если вы хотите изменить порт сервера, передайте его в качестве аргумента командной строки. Например, эта команда запускает сервер на порту 8080:

ps aux | grep manage

ubuntu 3438 127.0.0 2.3 40256 14064 pts/0 T 06:47 0:00 python manage.py runningerver

Кажется, что IDE, VSCode, Puppeteer, nodemon, express и т.д. Вызывают эту проблему, вы запустили процесс в фоновом режиме или просто закрыли область отладки [браузер, терминал и т.д.] Или что-то еще, во всяком случае, я ответил на тот же вопрос раньше, вот ты это ссылка

Для меня это происходит потому, что мой запрос API в Postman перехватывается точкой останова отладчика в моем приложении… оставляя запрос зависшим. Если я отменю запрос в Postman перед тем, как убить сервер приложений, ошибка не возникнет.

→ Так что попробуйте отменить любые открытые запросы, которые вы делаете в других программах.

В macOS я использовал sudo lsof -t -i tcp:8000 | xargs kill -9 sudo lsof -t -i tcp:8000 | xargs kill -9 когда я забываю отменить открытый запрос http для решения error = That port is already in use. Это также завершает закрытие моего приложения Почтальон, поэтому мое первое решение лучше.

What Can I Do If the Port 27017 Is Already in Use When We Start Up the EAP Controller?

Note: Port 27217 of Mongo DB server is for the EAP controller 3.0.0 or later and port 27017 is used before EAP Controller 3.0.0.

When we start up the EAP Controller, we may get the error report “port 27017 is already in use” as shown in the picture below:

The port 27017 is used for mongoDB server, an important module for EAP Controller. If the port 27017 is already occupied by some other applications or processes, the monogoDB cannot be initialed, and thus it will lead to the failure of the EAP Controller.

Generally, to solve this problem, we just need to find out the process that is using this port and stop this process. Please note that, before you do that, make sure this process is not important for you and can be stopped, or you may need use another host to run the EAP Controller.

Here are the steps to instruct you find out the process that occupy the specific port and then kill it on the Windows 7 operation system.

Step 1. Find the PID of the process that the port is using

Open the Command Line of the Windows operation system, and type the command netstat –ano |findstr “27017” as shown below:

Find the process whose status is LISTENING, and the 2700 is the PID of the process. Please note that different environment may have different result.

Step 2. Find the process’s name

Type the command tasklist |findstr “2700” as shown in the picture below. The 2700 is the PID that you found in the last step.

Here the result is mongod.exe, and this is in my test environment, you may get a different result.

Step 3. Kill the Process

Type the command taskkill /im mongod.exe /f as shown below.

Note: this command may require administrator operation permission. If so, please run the Command Line as an administrator.

After the process that occupy the port 27017 is killed successfully, it’s recommended to check it again with the command netstat –ano |findstr “27017”, after that, we can run the EAP Controller again.

If I just unplug it, plug it back in, then restart Ekos — it works. Any idea what causes this?

@Jasem, I regret to say that am still seeing the same error » [WARNING] Port /dev/ttyUSB0 is already used by another driver or process.» I am running astroberry 2.03 downloaded from the .img file. I have gone through this process indilib.org/get-indi/download-rpi.html Additionally I have done sudo apt dist-upgrade, sudo apt update, several reboots, I have removed modemmanager and gpsd. I am running this on a Pi4 / 8GB and have connected my Losmandy G11 Gemini-1 to both USB2 and USB3 ports. I have gone through power off of the Gemini and the Pi, disconnections of both. I have made sure that only the Gemini (and the USB 3.0 boot SSD) are connected to the Pi.

I do not know what to do next. I know this should work and I know that you know it works. What next please?

Replied by Hy Murveit on topic Port is already used error

In case you didn’t see it, I’m expanding on something said above.

It may be that your problem is the following: Linux randomly assigns serial USB devices to the ports /dev/ttyUSB0, /dev/ttyUSB1, /dev/ttyUSB2, . That is, the first device it chooses will get ttyUSB0 and the 2nd device ttyUSB1 and so on, but how it decides what is first is unpredictable. There’s a fancy scheme referred to above to help with with this, but understanding this is important. So, what I’d do if I were you is unplug all serial devices, reboot and only plug-in the one you want. I’ll bet you find that it connects now to /dev/ttyUSB0. You can then connect the next device, and I’ll bet it connects to /dev/ttyUSB1, and so on. Alternatively, you can keep things as is, and change /dev/ttyUSB0 to /dev/ttyUSB1 on the indi control panel connections tab for the device that’s not connecting and try to re-connect to it. Bottom line, this may not be a KStars/Ekos problem, but rather a linux one. Here’s the recommended work-around for that Linux issue: indilib.org/support/tutorials/157-persis. al-port-mapping.html

Thanks for your reply. Much appreciated. I did all you suggest many times. The Gemini (mount) never connects. I have tried it on its own with nothing else connected. ls -l /dev/tty* then shows no port suffixed by USB. Plugging my mount into either a Pi USB 2 or USB 3 port immediately generated a ttyUSB0 port. It never connects to KStars. The error message is always the same » [WARNING] Port /dev/ttyUSB0 is already used by another driver or process.»

In all honesty, I would not have written had I not been totally stuck. Finally, plugging my mount’s USB cable into a Windows 10 laptop it immediately connects to Stellarium either via Stellarium native or using the ASCOM driver.

This is very puzzling.

Rather, I think it was introduced by the latest INDI, Previously, all devices connected without issue.

My workaround is currently to plug in the usb cables one at a time -the mount must be the first connected- and hit connect for each device on the indi control panel. This is the only reliable way I can connect our eq6. Not elegant, but may help rescue a session.

If the devs need anything testing or if we could revert this section of the code to the stable version immediately before 3.5.3, please don’t hesitate to ask.
Cheers and clear skies,
Steve

An open port allows you to accept connections to your computer through the IP address of our VPN. For example, to run a game or web server on a computer and allow others to connect to it via the internet.

Preparatory stage:

1. First, you need to connect to our VPN. To do this, use a paid subscription or get a test code for one day
2. Download and install applications to connect. For example, for for Windows or macOS.
3. Connect to the desired VPN server and check, if your IP address has changed. If the connection is successful and the IP address has changed, proceed to the main stage.

Main stage:

1. Open the http://10.117.0.1 panel and log in with your code that you entered in the application to connect to the VPN.
2. Go to the Port forwarding tab.
3. Enter the required port in the Port field and click the Add/replace.
4. Рorts are added one at a time. If the port is not taken by another user, it will open successfully for you, and the rule will be added to the table below. Port openness should be checked from another computer that is not connected to our VPN.

If the port is already taken by another user, you will see an error “This port is already used by another user”. In this case, select a different port or a different server. Perhaps the port you need will still be available there.

In case of problems with opening the port, recheck yourself according to these instructions with pictures.

Note. on IP addresses that are shared with other users, which are accessible to everyone by default on VPN servers, you can only open ports with a number higher than 1000.

You can open any port on dedicated personal IP addresses, including ports with a number under 1000. The rental service for such addresses is available to all our customers with subscriptions for six months or less. To request a price and connection, contact us.
