Hi @jrp
When you manually login try sign out instead of disconnect if its the VM that you are using. That might leave your bot as well without logout.
Please give more contest like its getting locked when the bot fails only? Or even in success scenarios and is it recurring?
If you login manually is the issue getting resolved or still persisting?
And is the os win10 . Because on it we observed similar behaviour
Please check you event logs from event log viewer on your system and see if there is any un unsual error
Cheers
