Hello,
I have the latest MacOS and a recent MacPro.
Currently, it's a bit annoying, that whenever I am a little time away from it and it locks the screen, Tunnelblick gets disconnected and I have to re-enter password and connect again.
It does not happen immediately, so a short screen lock keeps the connection.
Is there a way to prevent that disconnect?
Has it to do with any possible sleep mode it enters?
Thanks, Alex

Try unchecking the boxes for under "Computer sleep/wake" and "Fast User Switching" on the "Connecting & Disconnecting" tab of the "Advanced" settings panel, which you can access by clicking the "Advanced" button on the "Settings" tab of the "Configurations" panel of the "VPN Details" window.

Thanks for the info. I unchecked those, but had the same behaviour after being away for 15min.
I hope it does not require to save password?

Please post the diagnostic info obtained by following the instructions at Read Before You Post. However, skip step 11. Instead, click the "Cancel" button and continue with step 12.

Is there anything I can look for? Or essential parts I can copy without pasting the whole file?
I extracted the diagnostic, but as it's a company computer, I am not allowed to disclose everything.
