Unable to open Webclient.

We recently upgraded to V20, we are trying to have our remote users sign into the webclient to make calls, but when trying to navigate to the system via the FQDN they are being blocked by a watchguard SSLVPN sign in page.

That's actually the port forwarding configured on your firewall, and it is set to the Watchguard firewall login page; the communication is not being blocked, but rather where TCP port 443 is forwarded to.

You need to port forward TCP port 443 to the 3CX system instead.
