I can't login in and the ports are closed

[awebo net]

Hi Ortali

First of all, I don't know how to send yo a PM. Sorry

I just did a fresh installation of ubuntu studio 24.04. 

I have downloaded SoulseekQt-2024-6-30 and when I boot it I get this message:
"Inicio de Sesión fallido. Razón de fallo reportada: socket error."

It's been a while since I last used SoulSeek.
My username is wenceslao.

SoulSeek tells me that the ports are closed, however I have created a rule on the router to open them.

I have the firewall disabled.

I successfully shared a folder.

Could you please help me with these problems?

Thanks in advance
