I had to redo my unRAID server due to a corrupted USB thumbdrive from a bad power outage / brown out, and after getting everything up and running again using the latest version of unRAID (I was a couple of minor versions behind), I started having issues with getting the docker to run correctly. Investigation of the logs showed that openSSL was complaining "OpenSSL: error:0A00018E:SSL routines::ca md too weak" due to the cipher strength of my vpnunlimited OpenVPN ovpn file.
After a lot of trial and effort I determined that I needed to add the following line to my ovpn file
tls-cipher "DEFAULT:@SECLEVEL=0"
This fixed the problem for me. I verified that my VPN is working correctly with privoxy.
wasn't sure if anyone else had a better solution for this problem, so wanted to share my solution in case it would help someone else later down the road.
