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

I have the exact same problem! **** Apple Music!😠

I am also getting that problem. I tried turning off Apple Cloud Sharing and then I got this.

I'm still using the same Apple ID, so I have no idea why this is doing this.

Same here. And all songs are greyed out.

Same issue. Mac, iTunes 12.2.1.16

It's always something with Match...

Ditto for a couple of hours now. something wrong with iCloud.

Hello,

Same for me 😟.

It seems only affected Mac OS X.

I can access to my Apple Music's songs from my iPad Air.

Hope, it will be resolve soon.

Exact same problem here.

Not sure what the exact problem is, but not of the software on my Mac Pro is causing this problem. I do have both Apple Music and Music Match, so perhaps there is some error occurring there (or not). Same message:

Also, noted little cloud symbol in upper right:

Which, when clicked on produces some activity:

Finally arriving at an added symbol (with a cloud ruled out) on my latest playlist:

And when I click on the symbol, I get:

Which is ridiculous. I own all the songs in the playlist. What is with this software, Apple?

Maybe it was an iCloud problem that suddenly went away, but, for me, rebooting my (USB-connected) iPhone seems to have done the trick.

Same issue - I am just shutting Itunes until there is some answer to the issue.

same problem here

same problem over here..

Same problem here. I installed the latest Update this morning, and I assumed it was tied to that. After reading the comments here, it seems like a server side issue. Hopefully Apple is working on it.

I got the same error 😠
