Uncaught RuntimeException: Failed to listen on reactphp about reactphp

[clue]

Hey @kamyabsoft, welcome to ReactPHP! 👋

Failed to listen on "tcp://127.0.0.1:8080": Address already in use

This indicates some other process is already listening on this address (like some other Apache or nginx process). This means that ReactPHP was unable to listen on this address. Accordingly, trying to connect to this address will actually connect to that other process instead of ReactPHP.

You can try another port number or use the special port 0 to automatically assign a random free port. You can then use $socket->getAddress() to get the assigned address.

I believe this has been answered, so I'm closing this for now. Please come back with more details if this problem persists and we can always reopen this 👍

Thanks for your guidance
The method $socket->getAddress() show me free port 37423 and i us this port in my code
But again, the loading of the site was infinite for the first time. I clicked on the site address again and it gave the same error as above and not echo hello world
my adress : http://103.215.221.123/

You will need to change to your listening address to your public IP or the special address 0.0.0.0:0 to listen on a random port on all interfaces. It may always assign a different port, but in your example you should be able to send a request to http://103.215.221.123:37423/.

Also, are you running this example from the command line? Note that this should not be embedded into a "normal" PHP script using a traditional SAPI like Apache/nginx. The script will keep running forever and you should be able to connect to it as long as the process is running. You may also have to check your firewall settings if external connections are somehow restricted.

@kamyabsoft Happy to hear you're making some progress.

The remaining problem you're describing sounds more like a firewall issue than a problem with ReactPHP. To isolate this issue, you may also try running another server process such as nc -l 0.0.0.0 37423 and see if a connection can be established.
