Using same Lets Encrypt account on all CCM

Question
1

We have a Management Hub scenario (licensed).

On host1 CCM cert requests works fine.

On host2 I have imported the working Certificate Authority Account from host 1 with account URI and account key → Generate → Register contact. That looks fine.

But on a certificate request i get this error:

2026-06-03 13:08:02.502 +02:00 [WRN] Fail to load resource from ‘https://acme-v02.api.letsencrypt.org/acme/new-order’.
urn:ietf:params:acme:error:malformed: Unable to validate JWS :: JWS verification error
2026-06-03 13:08:02.502 +02:00 [ERR] urn:ietf:params:acme:error:malformed :: Unable to validate JWS :: JWS verification error

I’ve seen some recent reports of similar errors on the Let’s Encrypt forum so there could be an ongoing issue there. e.g. Can't generate certificate - Unable to validate JWS - Help - Let's Encrypt Community Support

You could try using another ACME CA account but it’s worth just waiting a few hours to see if LE need to resolve something on their side.

I decided to create a new account for each host, so problem solved
