Answer 1

Based on the Push Notifications page of the Calendar API developer guide, a valid SSL certificate should be installed on the webserver. You can check it out first if the SSL certificate currently installed expired or was removed.

Also note that invalid certificates include

• Self-signed certificates.
• Certificates signed by an untrusted source.
• Certificates that have been revoked.
• Certificates that have a subject that doesn't match the target hostname.

Another important item to consider based on the page is that the domain in URL used in the address value should be registered in the Google Developer Console

Hope this helps!
