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:
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.
Did some more testing to get some details. The error I am getting from Traefik is that Cloudflare cannot create the record because it already exists (PiHole already has the entries). If I delete the records from PiHole, Traefik can then create the TXT records in Cloudflare.
