What steps have you taken to resolve the issue?

Hi.
When I connect directly to the server I don’t have the above error.
Only the error shows is when connecting through Cloudflare proxy.
The problem occurs even in Maintanance mode.

What are the steps to reproduce the issue?

I don`t now
I tried changing cache and proxy settings - the problem still persists

Hi there @sh16,

Thanks for reporting this. I believe that many other Proxmox users are experiencing the same issue and I previously posted at Error "Connection error 501: Not Implemented" | Proxmox Support Forum

As far as I can see, nothing changed on Proxmox side, so this appears to be on the CF side. I’ll cross-post this to see if we can get more attention

I confirm that I have the same issue, but it only occurs with one Proxmox node. Please note that nothing has been changed on the Proxmox nodes
