Mac Calendar "Server responded with an error" message

Mine went bad again last night (around 9:00 PM PST). However, while in Calendar, going to Preferences/Accounts, and un-checking Enable Account; then re-checking it, solved problem. I've been good for 36 hours or so now, by just doing that a couple of times.

Again, for Apple team members who may be on this discussion group, we expect more from you. There is a reason that we all didn't buy Dell computers, and it has to do with more than hardware.

Upon waking my computer this morning, Calendar was showing the error.

Interestingly, it was the only program with Dark Mode active. Dark Mode should have been off as it is set to auto (on at night, off during day). Then, when I pressed "Try Again" on the error message popup, Dark Mode was turned off for Calendar.

again, it appears to be a problem with the servers communicating, this problem/issues lie with top apple staff. I wish they would acknowledge this instead of telling all of us to do all these fixes and make the problem ours instead of theirs.

At this point I can't trust Apple Calendar. I am moving to Chrome to view my google calendars. Apple Calendar worked after I rebuilt -- and that action removed the time zone information in my appointments. But now as you all say, it isn't working again. I have been adding events in different time zones to my google calendar using the different time zone support feature.

One thing I've noticed is that Google has support for the start and end time of the events being in different time zones, while Apple Calendar has support for the whole event being in a different time zone. I wonder whether support for different time zone for events is clashing somewhere between Google and Apple.

Also I hope everyone here has filed a Apple Support ticket. I have, and interestingly have heard NOTHING back from them. NOTHING.

This is a problem on Google servers. 3:00 pm PST to midnight PST Monday to Friday - PST their servers start to throw a server error. Apple needs to get the attention of Google with this and just dedicate some time to log in, show the error and Google can configure to not throw the error. If any of the people with support tickets can pass along links so we can add onto them, that might help... or means of opening a new ticket and reference that same issue - it raises the awareness to support

I agree - this is a Google problem. Some sort of passive aggressive anti-Apple thing - note that the iOS apps for all of the Google products haven't been updated for ages.

I have several Microsoft Office 365 calendar/email accounts and they work like a charm. Should have never migrated to Google from MS....

I have this problem too. It happens for several hours, every few days.

Apple will tell you to reset NVRAM, safe mode, etc. none of which should be necessary if they'd just make technology that works!

Of course, these remedies do nothing.

I've tried setting my reset rate to every 15 minutes instead of 5. One possibility is that Google is refusing the connection due to too many attempts (by me or everyone?)

I am having same issue on M1 mac book pro big sur 11.2.2, intell mac book air 11.2.2, intel mac mini Catalina10.15.7. Have tried all the proposed fixes except the whole nuke the caches thing. Really don't want to do that. Please fix. this is major issue as I need to sync outlook, iCloud, and google calendars, and google has most of m person calendars.

I am also having this issue and it is infuriating. It started happening last month (February 2021) just like it seems like it started for everyone else here. I have deleted all my gmail calendars and reinstalled them and first it seemed like it was fixed and then it went back to the same problem again. :-( I hope it gets fixed soon.

I pretty much can't trust that the native calendar and mail apps will accurately reflect the state of my gmail account. I've resigned myself to using Outlook (!) as my main mail and calendar app on my Macbook.

Nice job, Apple.

I went through the steps David Drahos outlined. Gmail accounts (n=2) show in the sidebar after, but now none of the calendars are displayed. They're still visible in Gmail, though. At least the error popup stopped?

OK, so I'm on with Apple chat support and they are trying to be very helpful. But still don't seen to have a response from development or QA that they are following. They are having me do the usual reboot, load latest OS, etc.

So far 3 reps on chat haven't heard of this issue yet. Are you all registering this problem with Apple I hope :-)

I can confirm that the Dev team at Google is actively investigation this to pinpoint the cause. As soon as we hear back from them I'll post an update at https://support.google.com/calendar/thread/98473879?hl=en

Howdy,

Please also see and post on Google support forum thread:

https://support.google.com/calendar/thread/98473879?hl=en#

I have yet to hear back from Google WorkSpace support's escalation regarding this issue.

--

FYI: I was first alerted to this issue with macOS Apple Calendar application error messages, and indeed, seeing the same error messages :

"Access to account “Google” is not permitted.

The server responded

“403”

to operation CalDAVAccountRefreshQueueableOperation.

"

As I'm also an IT Consultant, with a paid for Google WorkSpace account, with support, I've registered this as a trouble ticket, and hope to have it escalated for resolution.

FYI: I was also able to reproduce this myself, directly, on 2 computers, with 2 different macOS versions, Mojave & Catalina (10.14 & 10.15), on BRAND NEW USER ACCOUNTS, created from scratch (ie: Thus, THERE IS ZERO CACHED DATA, nor account setup of any kind, so, it's all new), entered in my professional Google WorkSpace credentials, and the Apple Calendar application similarly fails to show ANY data at all, nor any error messages.

Hopefully Google WorkSpace support can escalate this issue, and get some attention on it, towards getting this issue resolved, as it appears to be a wide spread issue affecting many users on many different computers and various operating systems.

So, just to be clear, this is GOOGLE server side issues, and not client side, nor cache cleaning, none of which will work.

Thanks,

Daniel

I am still seeing this issue across at least there different macs with three different processors and OS versions, and none of the "fixes" really fix it for long, including the cache removal. What is interesting is that I have now noticed it seems to happen at certain times of day. Yesterday I noticed it at night from about 9pm till I went to bed at 12m. Today when I got up, the calendar was working perfectly with Google syncing correctly and zero errors. This was on all there machines and it worked fine all day today, until about 8pm, when I noticed that all machines were showing the grey error triangle on the Google calendar again. I will continue checking and noting times, but I wonder if there is some server process that is run each day at Google that is interfering with the server responding?
