I'm currently experiencing the same issue as cherritaker. Same info except I used /mnt/cache and it's a new container.
Unfortunately I'm not sure what's going on looking at the openvpn logs.
Full logs here if needed.
Additional Info: Seems to be something wrong with this server. I have another server that I just installed the container on and it works fine. The server the issue is on is newly setup and going to replace the other one.
