Hi!
Not so long ago I started working in my personal server using Proxmox.
Then I setup my WordPress server, created SSL certs and added another LXC to run NGINX Proxy Manager (NPM).
It was running just fine until some days ago...
If I try to open my website I get: 502 Bad Gateway openresty
I thought that it was NPM or openresty causing that problem, but I can not find anything wrong there (I'm not an expert in this).
