I was controling my remote computer for more than one month and suddenly the connection lost when I was using it. Then, I got message "Authentication Rejected" when I tried to connect again.
I hope anyone can help!
This is usually caused by some unforseen conflict with the TeamViewer service.
A simple reboot of the remote computer you are trying to connect to -OR- a restart of the TeamViewer service ought to do the ticket.
I can not access the place of the remote computer in this period.@JoJoJones
