Container stuck on /root/wireguardup.sh due to DNS resolution failure

NOTE: Attached file is .txt just for sharing purposes. The file is .yml on my server.

Earlier today, I installed Wireguard on Ubuntu Server 20.04 LTS in an attempt to switch over from OpenVPN. The first boot of this container worked flawlessly and download speeds were much higher than with OpenVPN. However, since that first boot the container refuses to work. No response from dig or from trill. I have another container with the same wg0.conf file that is working flawlessly (after multiple stop/start of container).

docker-compose file attached and output of some system commands are below.

@binhex I'm not an expert, but I can follow instructions. What else can I provide here to make your job easier?

I believe I'm having a similar issue. Did you resolve this?
