Could not create socket

#1 Post by tbarnes76 » 2021-01-21 14:07

This server has been running fine up until the other day. Now randomly I will get this error and the only thing to resolve it is a reboot of the server. Any ideas what the issue may be?

Something on your system (AV/security software) blocks the FileZilla Server service process from opening sockets to listen on, or all usable ports are exhausted.

If it's not AV, how can I know if all usable ports are exhausted?

No easy to answer. What ports did you tell it to listen on (Custom port range, Passive settings)? If the range is to narrow, it can easily run out of ports, depending on load.
