Out of the blue, contacts no longer sync

Just recently (like maybe just today) my contacts no longer sync.  I get this error:

7:48:29 PM   MailClient.Storage.Application.OperationException: Synchronizing folder ‘joe@redacted.com/Contacts/’ failed due to the following error: Execution of request failed: https://www.google.com/m8/feeds/contacts/default/full (Internal Error)

This used to work fine, and nothing has changed on my Google account.

Any idea what could be the problem?

Hello Joe,

We are aware of this error. It’s problem on the Google Contacts’ side so hopefully it’s just temporary and they will fix it soon.
