I'm having the same problem with web meetings just as Yetiman.
Early this morning it still worked and an hour later it stopped working.
There has been no changes to the server, firewall or 3cx settings.
I have tried to change regions and it still won't work.
I tried to see if I could get a connection with MCU's and the only one I get a response from was wmr.3cx.net, but from the MCU's I can see that SYN is send and there is no ACK.
It's not a problem with that port 443 is blocked in the firewall because when I use in Powershell Test-NetConnection google.nl -Port 443 on that server then I get a connection.
