Plex isnt connecting to server after update, what do i do?

I just downloaded and installed the new update. my server was connected and remote access working as well. After I installed the new update my remote access wasnt working and wouldnt reconnect. So i proceeded to disconnect my server and now i cant connect. Any tips as what to do?

Same problem here.

Hi, I was able to fix this problem. Try to readd Plex Media server to firewall exceptions.
(My windows is in Czech, but it should be easy to find).
