I don't know if I should be asking this here on in Pi-hole's forum but here we go. 🤔

 

I have set a DNS Record in pihole to resolve unraid's IP to a local hostname (192.168.1.130 -> unraid.nas) and a bunch of CNAMES for each subdomain.

Then NginxProxyManager resolving IP:PORTS to subdomains, the usual stuff.

 

In Unraid's network settings the DNS resolver points to Pihole at 192.168.1.20 and everything is fine and dandy.

 

Here's where my issue really starts:

I want to remove Unraid from Pihole, I don't want Pihole to filter Unraid's DNS queries because my Unraid is very noisy and It's not blocking anything anyway, so I changed the IPv4 DNS server to 1.1.1.1 and now I can't no longer access my services through subdomain.unraid.nas. If I return to 192.168.1.20 it works again.

 

Looking at the NPM log I can see that it's complaining a lot:

nginx: [emerg] host not found in upstream "unraid.nas" in /data/nginx/stream/1.conf:12

 

I understand that NPM can no longer resolve unraid.nas and that's why it's not properly booting and of course that's why I can't access my services through subdomain.unraid.nas.

 

Now, how could I fix this? Is there a way to edit the HOSTS file where I can point it to the right address? Modifying the hosts file does nothing sadly.

 

Thank you very much for the help.

Turns out I just needed to edit /data/nginx/stream/1.conf in appdata, restart NPM, and then change all the proxies from hostname to IP and everything is working fine again.
