Could not establish connection to Steam servers. (Result = 18)

Im trying to start my gmod server using Pterodactyl panel, but the problem starts at the moment of starting the server. all ports are currently open, but the connection can still not be made. once i start it, the server starts loading as normally, but then this error appears twice, and the server stucks there and wont continue loading. this is my server log:

Lance, its related to the node IP or server IP, cant remember how i fixed it

Met the same problem. On the Internet, the answer to the decision found. As a result, I decided myself: the problem is in this command "sv_setsteamaccount". Removed it from autoexec.cfg and it all worked.
