I have a problem to connect to the OpenVPN Server from my Mac with Tunnelblick. I installed the App on my Cloudron, set a device and downloaded the .tblk config file and inserted the file to Tunnelblick.
On connecting I always get the error "athentification failed".
Anyone an idea what could help?
Here are the logs from Tunnelblick:
