LetsEncrypt error: DNS name does not have enough labels

[Caveman]

I swear I've read about this before but couldn't find it during my search. I'm on firmware 384.7_2 (the latest release at the time of writing this) using Namecheap as my DDNS provider. The status under Server Certificate says "Authorizing" and under the system log it says, "urn:acme:error:malformed" and "Error creating new authz :: DNS name does not have enough labels".

Any ideas why this is happening and how to resolve it?

Oh I found it! Since I couldn't delete this thread, I'll just post this answer. Is this still the state of the situation?

Namecheap implementation is a bit of a special case compared to other DDNS services, as parameters aren't provided the same way as regular DDNS. DNS-o-Matic would be another special case that might prevent it from working with Let's Encrypt.
