My setup should be correct, because this was working for two months. The firewall checker show green across the board and I have the ports forwarded and access rules in my firewall, as well a SIP ALG disabled. But for some reason 2 weeks ago, when I punch in my static IP:5001, it no longer connects to my 3CX installation. Of course this means the FDQN doesn't work either, though it's not the FDQN fault. Any ideas what's going on? I tried restarting my 3CX server as well as stopping and starting the services, but still no dice. I haven't changed my firewall/port forwarding rules at all as well.
