I have an internal Nextcloud instance that I've been using for a number of years. I have a DDNS entry that redirects to my Comcast IP address and had been access that instance without issues. I reciently configured unbound in my Pi-Hole instead of using Cloudflare and/or Quad9. Shortly after, I was not able to access my internal Nextcloud instance. If I ping the domain name from any internal device, it resolves properly and give me my current Comcast IP address. I've got my router setup for port forwarding.
I'm obviously missing something.
I ender the domain name that resolved to my internal nextcloud instance. I am presented with the nextcloud login page.
