How can I access my local Proxmox server using a local DNS?

Hello, I have a Proxmox server and an Ubuntu Server virtual machine. On that virtual machine, I implemented a DNS service using two Docker containers: Adguard and Nginx-proxy-manager. Everything was deployed correctly, but now I'm having a problem: when I try to access Proxmox using the domain I configured, after logging in, I can't access my datacenter. Proxmox shows me a Connection Error 401: No Ticket

I tried both HTTP and HTTPS protocols and had the same problem.

I verified that the proxy host in Nginx has WebSocket enabled.

A AI chat suggested that one solution could be to add a local SSL certificate to my Ubuntu server, add it to Nginx, and assign it to the proxy host of my local Proxmox server. I'd like to know if there are any other solutions.

Thank you very much for your help.
 
What browser do you use? Are there extensions that might interfere with cookies?

What you can try if you didn't already:

* clear the cache of your browser
* disable all extensions
* restart your browser

> assign it to the proxy host of my local Proxmox server

This sounds like you are proxying PVE, which shouldn't be necessary if you really only want DNS.

Hi, thanks for your reply.

I tried accessing it with Brave and Edge, and to avoid cookie issues, I did so in incognito mode, but I'm still having the same problem.

I'm trying to access the PVE through the proxy, as it's one of the many services we have on the network. It's a corporate network with cameras, access points, and switches. The idea of using a DNS server with a proxy manager came about because we were having trouble remembering the IP addresses and ports of our services.
