I have a remote computer I use to connect to a few times a day,
It appears on both my "Last connections" and my "My computers" lists
Yet, lately when I try to connent, it disconnects immediately, so the connection is active like 6-7 seconds, and shuts down as soon as it should have displayed the remote computer's desktop.
Sometimes if I go ahead and close TeamViewer completely, including all the active background processes, and re-open TeamViewer, I can establish a connection, but it only once...
I do have a paid license, so it must be something else.
