Q: Unable to connect to iCloud music library

Same error here, but for me even by my iPhone now is impossible to connect with my iCloud music Library.

I'm downloading now the iTunes update (12.5.1).

I hope this can resolve this issue...

as of now, no popup with File > Library > Update iCloud Music Library -- turning black-lined circle appears for a while and then disappears -- earlier it turned into a yellow warning symbol but that's not happening now

I'm having this problem too, even on my old macbook running 10.10.5.

This error showed up with the older version of iTunes, got prompted to upgrade iTunes, then had the same error pop up after that update. Seems like the problem is on the server side, not the client side? It's driving me crazy not having a local copy of my library anymore seems like a mistake.

Why are you posting unhelpful posts. Servers go down. The complexity of the iCloud servers is insane. Google has outages, Apple, has outages. It just happens. Mine is working just fine now. It will just take a little bit to get them back up.

Not sure why you would think it's not helpful, perhaps you've noticed people talking about which software versions this is happening on, and if it's happening on their phones or just in iTunes. This is how one narrows down if the issue is server based with apple or something happening on your own computer.

My response was to SDZiech not you. Sorry they always post replies at the bottom which is confusing. Your message was very helpful and useful.

Touché. Hopefully it's just servers being flooded with login requests after the updates today.

Same here. Apple’s servers are probably overloaded due to the various updates rolled out today (iOS/watchOS/tvOS). Let we see tomorrow when the dust will settle down.

This problem popped up on my MacBook Air, running MacOS Sierra 10.12, before the iTunes update. Tried logging out and in, quitting and restarting iTunes, rebooting system, no change. Updated to new iTunes, now getting error even trying to sign in to my account.

iTunes is only showing songs physically on the MacBook.  Not showing the thousands of songs that are located on the server drive which is designated as the iTunes media folder location in iTunes preferences. No access to iCloud via iPhone either, which has been running iOS 10 through entire beta test period.

Also there is NO Airplay ability when listening to Apple Music stations on MAC after this update
