0 Sol/S... What to do?

Every time I fix a problem I run into another…

It currently says
Network solution rate: 0 Sol/S
Block height: 0
Connections: 0

It says I am mining with the tromp solver on 2 threads. I just set up my node using Linux Ubuntu.

Any ideas what I should do? Preferably in simplified language… I have no background in computer science

I have no idea about the rest of this… maybe mining isn’t what I’m cut out to do
