Public server with error 10060

Continuing the discussion from Connection terminated on my own server:

I have an error on my public server, I can’t log into it, error 10060 appears, on other servers it works, but on my 2 public servers not working, I’ve tried everything, disabling firewell, disconnecting and connecting the wifi, but nothing works. Since I put the USB WiFi on my PC it doesn’t work anymore.

You most likely received a new IP lease.
Check your PCs LAN IP and the port forwarding rules.
Disabling the firewall won’t help
