Slow/lag after reconnection

Using v14, up to date on host, previous update on remote. If my connection/internet breaks and I have to connect back again to the remote PC, it starts to lag and even auto disconnect the session after a minute. This happens as well usually when I put the remote to sleep and connect over wake on lan later. I need to shutdown the remote PC for it to work well again.

Sometimes not even a reboot will solve the lag. I have to wait a day or so...

Could be the tether function on my phone as well, as I'm connecting through it. Probably I have to disable it and enable it, the same for my 4G connection.
