This problem occured after I tried to join a server while I was in another server.
I have tried things like relogging, restarting my computer, changing my wifi connection, shutting down the firewall, deleting and reuploading TS5 but it is still “Disconnected”.
It has been 6 hours and it is still “Disconnected”.
Check if you see any suspicious activities in your Logs %localappdata%\TeamSpeak\Logs\Default
If you are not familiar with reading logs, then stop the Client, clear all files from the folder and then start your Client. When new files have been created, upload them to the Forum via Drive/Dropbox so that we can have a look at them.
You can also try clearing your Cache %localappdata%\TeamSpeak\Cache\Default
