I made a new installation of Pihole on a Proxmox VM using docker compose. I recently switched from a normal installation of ubuntu server to proxmox. Pihole worked just fine on ubuntu server, however on the VM (that still runs ubuntu server) i get this error:
Both messages show you have an issue with SSL certificate, but Pi-hole v5 (the current version) doesn't use https. If you are using a reverse proxy, you need to fix the certificate and configuration.
Your expectations are not correct:
You are trying to access using https, but it should be http;
