Bitdefender Blocking Inbound Port Access

I have a music streaming server program that requires a port opened for inbound access from external networks.


I defined a port forwarding rule in the router and verified the port is open and reachable in the local PC.


I can only access the server from the outside if bitdefender firewall is turned off.


No access blocking event is listed in the firewall log.


How can I fix this issue ?
