Q: Can't login to iMessage and FaceTime

Glad to see they're acknowledging a problem! Hopefully this is fixed swiftly.

We had this problem several months ago when we created an Apple account for my wife and bought her a new iMac. Neither Facetime nor iMessages would allow login. I could login from her computer with no problems, but even changing to a different computer made no difference. We talked with Apple support for hours and eventually worked up to an upper level supervisor (in England no less) who said it was an account problem on Apples end and Apple engineers would have to investigate what was wrong with my wife's account on their end. He said it would take 24 hours or less. Sure enough about 10-12 hours later my wife could login and it has all worked ever since.

Note that we did nothing special to the installation of the OS on the iMac. They even did remote access and could find no problems and indeed at their level (Apple support) my wife's account said it was valid. So the question is whether this is a software update issue or something getting flagged incorrectly in people's accounts on the other end with Apple's interface to the servers. If people are experiencing the same problem we had with my wife's account, the problem is not their computer nor the software update.

Back to My Mac also does't work for most affected but it doesn't marked as red. I'm worried.

Same problem here but I am running Yosemite. Messages just stopped working, signed out and now cannot sign back in.

I have the same problem and I am using Yosemite. It is an Apple server problem.

The Apple System Status page is now showing it as an issue but did not do so initially, so the entire page is worthless.

Worthless indeed.

After the El Capitan 10.11.4 update crippled my trusty old white mid 2009 Macbook(consistent kernel panic at boot) I had to reinstall from scratch. Done so twice, cost me a couple of hours, had a completely functional El Capitan install but no iMessage nor Facetime. Then called Apple Support, where, after being on hold and on the line for more than an hour(!) some senior support engineer told me that I would have to reinstall from the original DVDs that came with the Macbook and then upgrade to El Capitan. Some BS story about drivers not being in the El Capitan recovery partition. So another reinstall from Snow Leopard to El Capitan later and STILL no working iMessage and Facetime.

The fact that some service fails for some reason is understandable, I am in IT myself and I know for a fact that things can be unpredictable sometimes. But the communication to the customers about this issue has sofar been quite less than stellar, better information would have saved me a lot of time...

Hope they fix it soon! I'd really like to use Messages on my laptop

Good news, seems everything is OK now.

I can login now on my Macbook and send iMessages \0/

After a clean install of El Capitan, i had the same problem for about 24 hours (i've tried all the possible solution without success), but this morning, strangely the problem get solved by it self.

For same reasons the last version 10.11.04 as a lot of bug. i hope that Apple is going to fix it with an other update as soon is possible.

Wow, everything works now!

Finally it looks like Apple have fixed the issue, all working ok now

My issues fixed also after call to Apple Support, not sure if it was coincidental though with a global fix by Apple...

Finally everything works like a charm

Sadly I've been fighting the seemingly same issue with Apple for about 8 months and they can't seem to resolve the problem.  It appears that we need to create bug reports (http://bugreport.apple.com/) and really complain to the proper venue here because, while this is not new, it is a real nightmare to resolve.  I've been able to reproduce it in a virtual machine fresh vanilla install of OS X 10.11.  For those of us who have not seen resolution, please keep pounding because there is most certainly something askew on the server side from what a couple folks have told me who work at Apple, even though they can't seem to resolve it (for everyone).

So I'm still having the issue

"There was an error connecting to the Apple ID server."

I checked in Console and every time I try to login I see this 3 times.
