Port forwarding not working

I had set port forwarding rule on my router through the app but it doesn't seem to work. I went to try and setup port triggering, but it said port forwarding exist for the port. Is there any fix for it? or I might have to call again!
https://ibb.co/BB95GjS Port forward for 18080.

https://ibb.co/xCkRHsZ All traffic is blocked.

https://ibb.co/8sBf1KS Firewall is not blocking the traffic on the port in Ubuntu.

https://ibb.co/0mCXPS0 Port 18080 is still blocked.

All in all, the port forward is not working through the app. Any way to fix it?
