eM Client got an error message from GMail: An error occurred, Daily Limit Exceeded.

I got an error message from eM Client saying that “Synchronizing folder list failed due to the following error: Daily LImit Exceeded.” What is this, has never happened before? Seems that eM Client works OK though…

Is this the same problem as Manuel just asked about at https://forum.emclient.com/emclient/topics/google-contacts-daily-limit-exceeded ?
