Firewall Checker Fail

[techs221]

Hello I have followed everything I have found to configure my 3cx server with my firewall
When I run the firewall checker I get testing port 9308... full cone test failed

I am using Unifi Controller for my firewall
I have attached pics of the ports I have forwarded (I have removed IPs and unrelated ports from the pic)
and a pic of the firewall settings
The firewall checker is only failing on the one port 9308

Unifi controller isn't a firewall, it's a controller. You'd either have USG, USG-PRO, UDM, UDM-PRO. Your rules look mostly correct. You don't need STUN open. I'd make sure you don't have 9038 in one of the rules you have blacked out.
