3CX 20.0 Update 8 (Build 1109 Release) - Potential FQDN issues

[nathanfava]

Came into the office this morning, unable to get to the 3CX portal via fqdn or use the mobile/ desktop apps (apps dont show ext status however can make and recieve calls when in office)

I can get to the portal via internal IP, firewall checker passes, no changes made to network or fw rules

I can see our license automatically updated from NFRs to Enterprise Plus (ENT+) .

This update installed last night on the 3cx console

no lopnger able to ping fqdn also externally, okay internally

Are you using a dynamic IP as public IP?

Hello,

DNS resolution looks OK from here, although I cannot connect to the PBX due to I assume firewall rules on your end. Can you confirm reachability status at this point in time?

Hi,

After closer inspection, what seems off is that the TLS certificate on this machine did not update in a timely manner - does the server have any restrictions blocking communications with LetsEncrypt? You will have to force a certificate renewal.
