Any soulseek/nicotine+ users here who were able to do port forwarding?

I can’t seem to open my ports in both clients, my soulseek diagnostics says:

[jue. ene. 13 15:13:56 2022] Initializing UPnP

According to my router setting UPnP is activated, and whenever I manually try to make a rule, it disappears. I’m wondering if this has something to do with the OS, since I was doing just fine on Windows with this issue.

Strangely when i check my port status it returns as closed

UPnP is not active, any special rule in ufw and Nicotine works perfectly that way, have you tried to test a download ?
Here how looks my config:

I can actually use the clients, but not like before, port forwarding helps you connect to more users and more search results.

Solved it, it was a firewall issue.
