I am facing the same issue. The server where we have installed the certificate is linux machine and the CA is Entrust Certfication Authority. I am not sure the issue is with CA whihc is not recognised by Meraki or there is anything else???? When we open the website, the Certificate information and status is OK but once we validate it throws the error. Failed to validate with status code: 400, error message:Untrusted Server Certificate – Please ensure you are using a certificate signed by a valid Certificate Authority (CA). Need very urgent support.
