bind port php

vendorids

I reserved port 21750 through DevilWEB, but I can't connect to it via the Internet. The connection was reset
tried it in different ways
socket_bind(..., '0.0.0.0', 21750)
socket_bind(..., '127.0.0.1', 21750)
socket_bind(..., 'my_login.serv00.net', 21750)

There is no process listening on the specified port on your hosting account. Therefore, you cannot connect to it as there is nothing running on it.

I do not understand what it means. Right now my script is not running. But when launched I can't connect.
Are the ports on your hosting available for access from the Internet? Or are they only for local use?

vendorids Since you haven't launched any application on the server that would listen on the given port, how do you expect to connect to a port where nothing is listening?

I only ran the script for testing purposes. And nothing worked.
Now I left the script running and did not finish it. Now the port is being monitored, but again I can’t connect to it from the Internet

vendorids Your application is listening on all IPs and is accepting the connections, after establishing the connection your app disconnected the client. Check your code.
