My remote host is Mint 20.2
I installed TV 15.40.8 this morning and used a laptop to test the connection.  I used the web browser version. When I saw my remote screen come up, I left the app.
Now, I am playing with it, again.  I made several connections, but only shift and arrow keys were being sent to the remote. After a third or forth connection, the remote went offline.  I connected to the remote by ssh and can see that teamviewerd is running. Just for the heck of it I restarted the service, that did not help.
Any ideas about why it would suddenly stop taking connections?
