Access Proxmox using a domain

Hi

I've created a DNS record pvedash.mydomain.edu.ar pointing to an nginx RP, just to avoid using the port.

I can access PVE using such domain but can't open any console, just got a timeout error. However, if I use the IP:Port combination it works as expected.

So, to be able to access the console, do I need to avoid using a RP?

Thanks in advance
