I have a few different instances of Piholes running for different networks within my home. All except one of them are on Proxmox as LXC. One of them is installed on an old minipc running dietpi. I was able to set up all my LXC to work with Traefik using middlewares and adding a virtual_host configuration to my LXC settings. However, I do not know how to get it working for dietpi. So basically my domain points to the login page but once I login I get the following:
Failed Host Check: pihole.domain.com vs 192.168.10.07, pihole, pi.hole, localhost
This was the case with LXCs as well but once I added virtual host name it works fine now. But I do not know where to add this virtual host configuration in Dietpi.
Hmm issues seem to be with Traefik because I did some testing using native Lighttpd + SSL and NginxProxManager + SSL. In both cases I was able to login to PiHole without issues.
Uhh wait, there is exactly your problem describe on the last post. Seems you are not only one having this issue. Or was it you adding this post? At least IP address seems to match.
