502 Bad Gateway error when accessing Proxmox through Nginx Proxy Manager

I am encountering a "502 Bad Gateway" error when attempting to access Proxmox GUI externally through Nginx Proxy Manager. Locally, I can successfully access the Proxmox GUI using the IP address and port ( However, when I set up Nginx Proxy Manager to allow external access via proxmox.mydomain.com, I receive the "502 Bad Gateway" error. Upon checking the Proxmox server using tcpdump, I can see the traffic, but it seems that Proxmox and Nginx Proxy Manager are unable to establish a successful connection. I have verified my configurations but I'm still unable to resolve the issue. Any guidance or insights on how to fix this problem would be greatly appreciated
