I have a dedicated server(IP:27015).
BUT! On this port it will be connected it is not possible, external web services say that the port is closed. At the client the command connect ip:27015 does not give result (.
My server without problems is visible in search steam master servers. But, connection occurs on other ports which vary with each restart of a server (for example 17774, 22531, etc.).
Port forwarding on router set correctly (other services work), firewalls are disconnected, antiviruses are not present, the local port 27015 at hlds is present. Viruses are not present.
Questions with a similar problem in a network found, but answers to them are not present. Replacement 27015 on other values does not result in desirable results.
Checked with the help qstat and setti.
Sometimes the server can be visible not for long.
