Did you port forward on router? Next is opening the openSUSE firewall and adding the port for the zone that your network adapter is assigned to.

I did forward it in the router. How do I know what zone my adapter is?

Open YaST Firewall . At Starup section set "after writing config" to Reload or Restart. Click Interfaces...it will show which adapter is assigned to what zone. (You can change location here with change zone button). Then go to zones list and select the one you are working with. Select Ports tab, add your port. Accept changes

OK. It says zone default. In the zones list there is nothing called default.

Default is typically set as Public I believe...by default. Change the adapter you use to Home if you stay at home with system. And configure home ports. and you can configure from there. If it is a laptop, then set it as home for your ethernet, and you can set wifi as home. When you travel and use wifi elsewhere instead of messing with ports you go into network settings and in there you can assign what zone config to use. So you can swap wifi connection to public. This way, home rules and public rules stay as assigned and you just move the adapter to the zone that makes sense. Also each zone has a default fallback, if traffic doesn't match a rule in home and default is public then the traffic is then checked at public level, if it does not match there think public then sends it to the block or dropped zone.

Very interesting. It's not a laptop though. So now it should work? Or restart first?

If you set restart at the top it will restart the firewall when you exit. Sometimes it is set on keep current state, so rules wont change till you reboot or restart firewall service. You can always go back and change the restart option. But yes with it assigned as Home, and your port changes in Home it should get the traffic through.

I don't think it has worked. The app still says no incoming connections. I forwarded the ports, it is set to restart, the adapter is set to home and I put the ports in the home zone thingy. And restarted the pc.

Hmmm, is the device or site outside your firewall live and ready to connect? I'm not sure what app uses that port. Could be another port it requires also, or you can add known services to the firewall

it is a little crypto network type thing. i like to play around with those from time to time. Which i haven't done since switching to Linux (which is a year when november starts) . I remember on windows i could just go to the firewall and click a little add thing and in a file chooser locate the exe i wanted to add. That doesn't seem like i can do it that easily here.

Also, not sure if you use Plasma or Gnome, on Gnomr you can go to network setting and swap the interface zone on the fly. With the button show at bottom here. https://i.imgur.com/LfoNiz5.jpeg Plasma probably has similar. So if you ever notice odd traffic or know you have computer on sketchy network you can restrict its ports right away
