Gmail Calendar, does not sync on program start

Version: 8.0.2951 (e2fe9f0)

In order to get Gmail to sync the calendar properly I have to disable, then re-enable the connection to the Gmail calendar under the eM Client advanced settings.

Below is the error log.

As the sync with Gmail calendar works after I disable then re-enable the calendar connection, this is not a permissions issue within Gmail or eM Client. To make calendar sync work I have to do this every time I open the eM Client. This points to there being a difference in the commands run on program start up and when you manually enable the calendar connection through the advanced settings in eM Client.

It would be great if you could have the programmers take a look at this, as this is likely to affect all Gmail users.

Thanks.

What OS/Version are you using.
My Google calendar works fine.
What exactly do you mean by “after I disable then re-enable the calendar connection,”?
How man calendars do you have and do they all display the same problem?
