Problems with PiHole

Hello,

Thanks for a good software!
But I'm having problems running it with pihole.

I have a DoT local DoT proxy forwarding/translating incoming requests from 853 to Pihole which has upstream 1.1.1.1 it works fine.

When using Dohnut in docker, run with this command
` docker run --detach --restart unless-stopped --publish 0.0.0.0:531:53/udp commonshost/dohnut --listen 0.0.0.0:53 --doh commonshost --bootstrap 1.1.1.1`
It works fine on its own, dig @localhost github.com -p 531 gets a reply.

However, when setting the upstream in pihole to 127.0.0.1#531 i only get this kind of errors in the pihole log.

```
Dec 5 16:51:39 dnsmasq[31475]: query[A] play.google.com from 127.0.0.1
Dec 5 16:51:39 dnsmasq[31475]: config error is REFUSED
```

Any idea what could be the issue? :(
Thanks in advance for your time!
