I have set up acme-dns successfully on my server so that I can auto-renew wildcard domains.
I guess it's my desire to keep things tidy, but I can't see how to deregister a registered domain name that I misspelled. I can't see anything here about it.
Any ideas how to go about this? Maybe there's a file somewhere that needs certain lines deleting or maybe a whole file to be deleted.
What did you misspell and how? acme-dns generates a unique subdomain and credentials upon registration; the only thing submitted to it is a TXT record value. acme-dns has no idea what any registered domain name is.
for clarity, as that might sound confusing:
upon registration, acme-dns creates a new subdomain based on a UUID, and a new set of credentials
you CNAME the registered domain on your DNS onto the acme-dns subdomain
acme-dns never knows or cares about the registered domain
if you want to do overkill, and risk breaking things, you can manipulate the sqlite database directly. otherwise, it's just a few bytes of deadspace in the file.
