CADDY Reverse Proxy Support

[jeffsui]

Hello,
I'm having some issues proxying Proxmox behind Caddy.

If I hit my box on its direct ip address the console opens fine.

If I hit the box via CADDY Proxmox loads fine but the console throws a wss://xxxx error




My assumption is that I'm missing some directive in caddy but I'm kind of at a loss. The only info I can find out there regards to nginx...
