I had a container restart after a weekly backup and it was suddenly unable to connect to my VPN provider. The config didn't change. Looking at the deluge supervisord logs, I was continually spammed with the following error.
704 DEBG 'start-script' stdout output:
OpenSSL: error:0A00018E:SSL routines::ca md too weak
Cannot load inline certificate file
704 DEBG 'start-script' stdout output:
Exiting due to fatal error
I looked up the error and found a solution that may help. I had to add this to my OVPN file and the error went away.
