I am unable to port forward, i have also allowed the firewall so i would like some help, this is a new router and worked before

If it's a new router connected to a cable modem it's likely that your WAN IP address has changed. Maybe that's the problem. How are you testing this?

I am testing via a laptop on the same network, i have 3 instances, one with local ip, public ip, and a custom ddns (lower priority), both public ip and custom ddns do not work, so it seems to issue is with the port forwarding

Testing internally can sometimes be misleading because it relies on NAT loopback. Try doing a port scan from the internet.

As expected this was the result

For extra info, the first 6 digits of my WAN IP is 100.109, i see a post with a similar issue mentioning something about CGNAT, could this be the issue?

Yes, that will be the problem.
