Weird networking issue, seeking help (piefed.ca)

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?

Is your pihole server the only DNS server set? Either on your PC or router? Is network manager sometimes using a different nameserver?

How would I check that?
