Hello. Can I use external nginx LXC (proxmox) server instead of NGINX plugin?
Currently I am already using it, but together with configuration.yaml ssl certificate,which I downloaded from external nginx server and put certificates under ha\ssl
EDIT resolved. Issue was, that in external nginx proxy manager I did not change scheme from https to http, when removing ssl certificate 
Thanks @mobile.andrew.jones for such a detailed description in this thread: I have tried everything and I cannot for the life of me get reverse proxy working. [please help] - #6 by mobile.andrew.jones
