The "error -1" means that no data was returned by the server. That could happen for a couple of reasons. One possibility is that the server is having a temporary problem; in this case, the problem would typically go away within a few hours or days. It doesn't sound like this is your experience.
Second, as was explained earlier, there is a 9 minute throttle. That means that any request for calendar sync data made by any device less than 9 minutes after a previous request will return no data. You apparently have at least three devices trying to sync. I don't know how much control you have over the timing of the other devices, but it's conceivable that one device syncs every 20 minutes at :00, :20, and :40, and the other device syncs every 20 minutes at :10, :30, and :50. In that case, a third device would have little chance of syncing at all. Of course, that is a contrived example, but something like that could be happening.
You could eliminate that possibility by completely disabling the sync on your other devices, waiting 10 minutes or so, and then trying to sync on your iMac.
Questions that can benefit the larger community should be asked in a public forum, not a private message.
