Can't access my Node.js server with external IP address

Question

Here are the steps I've gone through to setup my server.

I've bought an Orange Pi 5, installed Debian from their website and started to configure it.

I ordered static IP address and in Firewall/Virtual Server I added port forwarding item with this options:

• description: HTTP
• External Port: 80
• Internal Port: 80
• Internal server IP: 192.168.1.10 // the internal IP of my Orange Pi server
• Protocol: Both TCP/UDP

Then I checked with this website https://www.yougetsignal.com/tools/open-ports/ if the port is open and it said yes.

Than I configured nginx to forward all requests to port 80 to localhost:4001 where my node app is running via pm2.

Now if I try to access my node server with http://192.168.1.10 it works but when I try to access it with for example http://91.232.11.238 it times out.

Also I checked firewall and it shows something like this (which I guess shouldn't be the reason why my external requests are not reaching my Linux machine):

Status: active
Logging: on (low)
Default: deny (incoming), allow (outgoing), deny (routed)
New profiles: skip

80 (v6)                    ALLOW IN    Anywhere (v6)  

Any help would be appreciated.
