The shared library “Cloud Music Library” is not responding. (503)

All is working fine again this morning, it is a miracle?

I was actually struggling with this problem literally earlier this morning. I had to chat with Apple and troubleshoot a whole ton of things to get the error to stop appearing. Now I'm trying to listen to music on Apple Music and it says I'm not signed in, when in fact I am. I think there must've been some glitch in correlation to the newest OX update which is El Capitan...

Im using Mavericks on my Macbook and iOS 8 on the iPhone.

Had the problem yesterday all day long. iTunes was not usable to me, because of all the annoying CLOUD MUSIC errors.

Today, it seems so, the problem has solved itself.

Got no more ERROR 503.

and i really really did nothing. so just be patient.

Exactly the same issue. Apple Music on iPhone working fine but NOT on the iMac. Getting the same error message and window.

The issue appears to have resolved itself this morning. The fact that many companies, including Apple, leave their customers in the dark about things like this angers me a little. In Apple’s case it only reinforces the perception that Apple is not all that competent in Cloud services. As an Apple Music subscriber I expect the service to be available 24/7/365. Trouble does indeed happen but I expect to be kept informed about estimated restore times. As we can see from the posts in this forum people were spinning their wheels trying to troubleshoot the issue, even calling Apple tech support only to be given the run around there too. In my case Apple’s “System Services Status” website was showing all green while I was having the very issue we all had here.

WOW same prob happened to me. Out of nowhere music was not available. I turned off my wifi and connected to my iPhones Hotspot and like magic, Apple music is available.

So strange...?!?!😝
