3 years ago I'm not familiar with Synology systems, but this error often indicates that you are not running the container in privileged mode. Please check if such an option exists at the general settings.

Hi,
First: I'm not the tech saviest guy on earth but I manage to get most things to work somehow. But here I can't get my head around what might be wrong. Might be sthg blatantly obvious, so bare with me please. And thank you for your work. It's highly appreciated.
I try to run the Docker container on my Synology NAS. I've set up the docker container as far as I can tell according to the instructions. I use an .ovpn file which works all right (tested it beforehand).

When starting the container I get this in the logs.
