Severs not appearing

It also affects every version, I just don't know how to make it say that.

What I expected to happen was...:
Severs to pop up and say they're pinging, unable to connect or able to connect.

What actually happened was...:
No severs popped up at all.

Steps to Reproduce:
1. IDK
2. This just happened randomly
3. Nothing changes even if I swap versions, if I re-add severs they don't seem to work properly.
