Issue with Traefik SSL and PiHole (lemmy.world)

I set up SSL certificates for my internal services behind Traefik, but I was having some issues obtaining the certificates. I ended up having to add this line in my Docker compose file to bypass PiHole which is controlling the internal hostnames for my domain:

- --certificatesresolvers.letsencrypt.acme.dnschallenge.resolvers=1.1.1.1:53,1.0.0.1:53

After adding that, I was able to successfully pull a cert. The issue is, I have a firewall set up that blocks DNS requests from everywhere except my DNS servers (PiHole), so I had to pause that rule temporarily to get the request to go through.

Wondering what I can do here (if anything) to resolve this without having to disable my firewall rules regularly.

Acronyms, initialisms, abbreviations, contractions, and other phrases which expand to something larger, that I've seen in this thread:

Fewer Letters	More Letters
DNS	Domain Name Service/System
PiHole	Network-wide ad-blocker (DNS sinkhole)
SSL	Secure Sockets Layer, for transparent encryption

3 acronyms in this thread; the most compressed thread commented on today has 7 acronyms.
