Hi
I had Nginx running reverse proxy on PVE machine and pointing to 192.168.101.1:8006. That worked fine with LetsEncrypt etc. I decided to remove/shut down Nginx running on PVE and have VM running Nginx and pointing to the same PVE local IP. However instead of Proxmox GUI I am getting blank screen. In /var/log/pveproxy/access.log I found:

192.168.101.9 is a VM running Nginx doing reverse proxy to PVE (192.168.101.1)

...
Any idea how to fix that?
 
Problem solved, Proxmox doesn't like:

Bash: 
add_header X-Frame-Options "SAMEORIGIN" always;
add_header X-XSS-Protection "1; mode=block" always;
add_header X-Content-Type-Options "nosniff" always;
add_header Referrer-Policy "no-referrer-when-downgrade" always;
add_header Content-Security-Policy "default-src 'self' http: https: data: blob: 'unsafe-inline'" always;

in Nginx vhost configuration.
