I'll try that as soon as possible.

I have to check this too.

It is all ok regarding the firewall. I'll try to create another server (plex or something). If it works then the problem might be on calibre side. If not, it is just me doing something wrong.

I've done everything suggested from tutorials and even the official site of the router provider. However, my knowledge on port forwarding is very poor, so I'll look this again.

Yes. I've tested from cellular network and asked some friends to try to access.

Thank you for pointing out those questions. I'll check all of them.
