teamviewer authentication rejected

[born2ride]

For the past week I have been unable to connect remotely to one pc out of the 4 on account , I have tried updating windows  and TV on the pc with issue. I can connect first time after reboot  and stay connected, but if i terminate then try  to reconnect i am unable and get authentication rejected until pc is rebooted.. It  seem to think this happened after last TV update.
What info can or should i provide???

EDIT :  I did update remotely on this pc

Which operating system?
Is it on the lockscreen of Windows 10, where you cannot login? If so, it is a known bug.
Other than that: Date, time and time zone match?
What is the exact error message you get?
