I run CachyOS on my desktop. I host Homepage for myself on a home server. This is reached at home.mydomain.tld. Pihole on my local network catches that request and points it at my local nginx, which reverse proxies me to the homepage.

Now, I set this all up a while back and it all worked totally fine for several weeks. Then, about a week or so ago, for some reason almost every, but not every time I boot my PC, home.mydomain.tld gives me a “cannot be reached” error in my browser… until I run systemctl restart NetworkManager and then it works completely normally.

Can anyone help me troubleshoot why oh why that would suddenly be a thing? Does anyone have suggestions of a way I can troubleshoot a permanent fix to this so that I don’t have to restart NetworkManager almost every boot?

      nmcli device show eth0

      Or replace eth0 with whatever interface it is. Will give you a list of all network parameters including the DNS servers. There ideally should only be one, your pihole

        There is only one IP4 DNS address, however there are two IP6 DNS addresses for my ethernet interface. However, I also notice that the GENERAL.CON-PATH ends in 2, whereas I have another interface lo which ends in 1. Would that be a clue of anything?
