Since updating to Big Sur, my google accounts have stopped syncing with Calendar. They would show the error triangle. When I click on the triangle, they should just say "error connecting to server." I tried the cache clean. I disabled and enabled the accounts in Calendar. Finally, I removed the accounts from "Internet Accounts," which is where I am now. The two accounts in Calendar don't show an error, but they aren't syncing at all. No error, but also no calendars from google. It just shows the account names and nada. Any help and/or others experiencing this?
Got a tip for us?

Calendar Sync w/ Google in Big Sur

Same has started happening to me. Was working fine on Big Sur but then yesterday I noticed the error triangle. I tried all the same things as you but my Google account won't sync to Calendar. I don't think this can be a Big Sur issue as before yesterday it was working fine and has been since I updated to Big Sur at the end of last year. Maybe something at Google's end?
You could try quitting Calendar, turning off Calendar syncing for all of your Calendar accounts, going to the folder ~/Library/Calendars, deleting the three "Calendar Cache" files in there and then re-enable syncing.
If that doesn't work…and all of your calendars are synced ones and you have NO calendars "On My Mac"…you could do the steps above and delete everything in that folder and let it rebuild from the server.

Thanks, I tried the cache already. Are you suggesting everything in the calendar folder can be deleted without issue? I'm somewhere between a complete noob and marginally tech savvy, so I know to be afraid of deleting stuff in the library.
Appreciate this heads up. I don't know 100% that it started alongside Big Sur, but it's been going for a couple weeks now for me, so figured it lined up.
Hi. It has just started working for me again! I haven't done anything over and above what I said in my previous post. All very odd!
Update: I have done nothing since posting this topic, and my calendars are up and running. the last thing I did was delete my accounts from Preferences (not from calendar), restart the computer, then add them back in.
The lack of calendars that was the case at the time of writing the initial post has now been resolved. No idea what happened, maybe it just took a long time to perform the initial sync.

Reporting realtime. I just got the errors again. The pop-up says there was an error connecting to the server. It pops up for each individual calendar associated with an account. Bummer. It was glorious while it lasted. All 6 hours of it.
This issue has been recurring for me since Thursday last week. I completely nuked my calendar in the process of clearing caches every which way. I left the rest of our office calendars untouched. The problem fixed itself over night after I spent hours researching and tinkering. Then it broke again. This week I noticed every single day at 3:45pm PST it goes offline. So every morning it functions perfectly throughout the day until the time it has self-appointed as quitting time. lol
I've got the same issue, on two different GSuite accounts, or whoever they are calling it today.
I get the error message about the server couldn't be reached, and then when clicking the error triangle I get a message
I've done the same cache clearing, I've deleted account from all devices and then readded. Sometimes one of those works or sometimes it doesn't. It almost like the exceeded Auth errors are causing rate limiting by google.
This lead me to find https://www.zdnet.com/article/googl...ure-apps-from-connecting-to-g-suite-accounts/ ( only article i could find with a date lining up ) which started Feb 15 to block less secure apps. My guess is while Apple appears to be using OAuth, they are not using updated protocols to sync the calendar.
Edit:
Following several links on their site i found this - https://workspaceupdates.googleblog.com/2020/03/less-secure-app-turn-off-suspended.html - but the original Feb 15,2021 date still applies to me and lies up to nicely.

Mine is working again this morning and I haven't made any changes. Suggests to me that maybe this is something that is happening at Google's end at a specific time each day? All very strange
Google has servers scattered all over…hosting their services…and problems that affect only some users have happened in the past. This is probably what's happening. To cause a connection error, all Google would have to do is lose (temporarily) their own DNS-type routing of your account to the proper server…and those routes are probably being switched around quite a lot. That they get it working at all still amazes me.
It's really sporadic. At least a couple times a day I see an error as described by the OP, but then at other times it seems to sync without an error. I'm seeing it on two Macs running Catalina and Big Sur, but not on my iPhone. Given that nothing's changed on the Catalina Mac in a while, I have to assume it's some kind of issue on Google's end.
I migrated all my calendars to iCloud a few years ago because of sync issues and it's been excellent -- but unfortunately still have to subscribe to a few shared ones people have on Google.

OK, so today the triangle is gone and all is working again in the calendar (for the moment)
