DNS problem: SERVFAIL looking up CAA for domain

Hi @clviper, this API announcement explains why this problem is occurring for you.

Not quite - you don't actually need to add a CAA record or have support for adding them. The problem is that when we ask your authoritative DNS server "Hey do you have a CAA record for this domain?" instead of saying "Nope, no record!" it says "SERVFAIL".

You need to contact your DNS provider to have them fix this error. Soon all CA's (not just Let's Encrypt) will be required to ask your DNS server about CAA before issuing and this will cause problems until fixed by your provider.

There isn't presently a way to bypass this error except having your DNS provider fix this problem or switching to a DNS provider that doesn't return SERVFAIL instead of a non-error reply.

Hope this helps!
