The certificate is not properly configured, or configuration changes are not applied.
Make sure that the new certificate is set in Hosting Settings of the domain;
In case of dedicated IP address, make sure that the new certificate was assigned to the domain's IP address and not just added to the domain's " Certificates " repository;
In case of shared IP address, make sure that Server Name Indication (SNI) is supported and activated;
