DNS Server Failure

Help
1

Hi! I'm new to the Pi-Hole space and need a bit of help.

I managed to install Pi-Hole just fine, but when checking the status it shows DNS Server Failure. I believe it has to do with the fact that my port 53 is already in use, although it says it's in use by dns-server as shown below when running sudo lsof -i -P -n | grep LISTEN.

dotnet    1464 dns-server  233u  IPv4  16561      0t0  TCP *:53 (LISTEN)
dotnet    1464 dns-server  235u  IPv6  16563      0t0  TCP *:53 (LISTEN)

Is that the expected behavior? What are the steps to fix this?

In this case, dns-server is the user name.

Your debug log shows port 53 is in use by dotnet:

[✗] udp:127.0.0.1:53 is in use by dotnet
[✗] udp:0.0.0.0:53 is in use by dotnet 
...
[✗] udp:[::]:53 is in use by dotnet 
[✗] udp:[::1]:53 is in use by dotnet 
...
[✗] tcp:0.0.0.0:53 is in use by dotnet
[✗] tcp:[::]:53 is in use by dotnet

You need to disable this service (or move it to another port).
