Issue with CT. Nginx CT as proxy for port 80

[xxashixx]

Hello all
Hope all is doing well with the craziness that is going on

So currently running a dedicated with one IP but need multiple containers that can serve port 80 each with their own internal/private IP. I have followed this guide the T but having issues with apt-get in the CT with port 80. Possibly because of the proxy? Network in the CTs were working fine but after I added the Nginx proxy everything broke.
SSH into the CT from outside works as well.

My setup is as follows

Hi,

this has nothing to do with Proxmox-VE in particular.
You can ask here, but I think this Questin is better to ask at the Nginx forum [1].
