after upgrade to 3.3 acme.sh fails [SOLVED]

Hello,
I just upgraded from 3.2.p12 to 3.3p1. I just created a website (dns hosted elsewhere) and tried to issue a letsencrypt certificate. Where this was working before it is now failing with:

"[Mon Jun 16 01:51:10 PM EDT 2025] response='{
"type": "urn:ietf: params:acme:error:malformed",
"detail": "Unable to update challenge :: authorization must be pending",
"status": 400
}'"
excuse the tongue stickout emoji. the editor put that in
The last time it failed, it failed before the upgrade because www didn't exist even though I chose "none" on the auto-subdomain. I just added the dns record for www and will wait an hour or 2 and try again. If anyone has any answers to this, it would be much appreciated.

Thanks,
Curtis

 

Solved.
Added a www dns record waited a day and tried again. It worked.

 

Hey Curtis, that error usually means the DNS change hasn’t fully propagated or the challenge expired. Wait a bit, then retry the certificate request — it should work once DNS updates.
