Origin SSL check fails with the NEW Letsencrypt Issuer

0

Certificates on the origin from Letsencrypt worked fine for years now.
Yesterday one of the ssl certificate of a websites got renewed successfully.

But now cloudfront makes a 503 error only for this website (one of many)
other website with an older certifacte from letsencrypt still working fine.

The only difference is that LetsEncrypt now signes with a new issuer
Old issuers was: "Let's Encrypt Authority X3"
New issuer is: "R3"

Issuer Certifactes
https://letsencrypt.org/certificates/

There are two Intermediate certifiactes,
this one make the issue:
https://crt.sh/?id=3479778542

Issuer Statement:
https://letsencrypt.org/documents/isrg-cps-v3.0/

It seams that cloudfront dont trust the certifactes from the new letsencrypt issuer "R3"

My hosting system virtualmin only renewed the certificate but not the Intermediate certificate.

After updating the Intermediate certificate manually it is working again
