I don't know if this is exclusively to me but I noticed a pattern; Whenever I go in the server list to find my server and back out after not finding it, so I can reload. Servers load again but if I do this one or two times more, servers stop showing up and I have to close the client. What I also noticed is that when this happens, my internet seems to not load any webpages except for google or already loaded pages and I have to wait around 5-10min to fix itself until I can load other pages and browse for servers within the client.
This has happened every time. My internet is a fiber connection and has never had any issues before.
