Are.you able to identify what dns provider youa re using, as I read the error as being related to the cert resolver not being able to access the correct zone from the DNS provider. I am using cloudflare and the Caddy file looks pretty similar to mine, so I aren't sure the issue is there.
One other thing to try is to restarts caddy, I found that sometimes reloading my caddy file wasn't enough, and thing seemed to stay working after I restarted the docker image
I presume this is in jest, but to be honest I feel like there is less risk of bad operators consuming my computing power and data when pirating than using legit services these days (ads, marketing, poor software etc...). I actually pirate content that I pay for as it gets all my content into a single location, and easily tracks what I have watched, and is better for taking it offline.
