Port forwardig partialy not working

[kanestar]

I recently installed Ubuntu Server 24.04 in one my PCs in my network. For learning purposes I tried setting up some servers. I set up a jellyfin media server and a web server with nginx. I'm able to access it inside my network. When i used port forwarding to access it outside my network, the jellyfin sever works with portforwarding but the web server doesn't work. When I checked for open ports with Port Checker - Check Open Ports Online . The website shows the port for my webserver(80) is closed. I also setup ssh. It works but not webserver.
FYI - these are the ports I forworded from router to Ubuntu server
Port for Jellyfin : 8096
Port for Webserver : 80(http), 443(https)
Port for SSH : 22

Try using custom ports.

Yes, actually custom ports are working. I'm trying to get a https ssl certificate from Let's Encrypt. For that port 80 needs to be open. Is there anything that I can do to get it working.

Haven't tried hosting personally. Must be configuration issue somewhere. Normally all ports are open on BSNL network. Check firewall and port forwarding configurations again.
