Hi,

After running fine for years I suddenly noticed the certificate for the acme dns server itself was not renewed. The Let's Encrypt renewal did not work. I was expecting acme-dns to generate the DNS-01 TXT record for itself but seems it no longer happens and therefor cert renewal or creation fails.

Any clue how to troubleshoot? Any changes on Let's Enrypt side?

Regards, Bjorn
