iTunes Store: Can't access Apple Account

Since you can sign in to your Apple Account elsewhere, I’d focus on iTunes for Windows rather than changing the password again.

First, make sure Windows has the correct date, time, and time zone. Apple specifically lists that as a cause of iTunes Store sign-in and secure connection problems. Also check Account > View My Account in iTunes in case there’s a billing or previous-purchase issue.

If those are fine, check the Microsoft Store for an iTunes update. Apple currently recommends using the latest iTunes version available there.

If error 301 continues only in iTunes, I’d also temporarily check whether third-party antivirus, firewall, or other security software is interfering with iTunes connecting to Apple’s servers. Apple documents that as a possible cause of sign-in errors on Windows.

I had to uninstall everything apple including apple tv, apple music app and iTunes.

Updated windows.

Restarted.

Installed iTunes.

And was able to sign in again.

Had scheduled call from apple support. They are aware of multiple users with the same issues.

A scheduled update on the 9th of September should patch the windows/Apple handshake issue.

And a scheduled callback on the 10th of September to see if it has resolved the problem. If not, they plan to track my loggins, so hopefully the updates on Wednesday the 9th work for everyone 🙂

I can confirm that today's update has rectified issues.

Not initially, but i checked for windows updates, downloaded recent security update, restarted windows pc, opened apple music app, username and password, and after a slight stutter, im now signed in and my library is loaded 🤞

There's a backward compatibility issue between apple and windows.

Apple have confirmed this though they are calling me back tomorrow, 4th September, to see if they can resolve. I can sign in via webplayer for apple music, but not apple music app on Windows, or iTunes app on Windows. Tried deauthorising computers, using someone else's apple account to see if that would be accepted and no, network settings, firewalls, reset pc, the lot. Nothing working

I’m experiencing the same issue and have tested several possible causes, including different network connections, proxy settings, and DNS resolution.

One of my test devices is an iPhone 6 running iOS 12.5.8, the latest iOS version available for that model. The login process fails at this endpoint:

https://buy.itunes.apple.com/WebObjects/MZFinance.woa/wa/authenticate?guid=mydeviceid

Normally, I would expect the authentication flow to redirect to an assigned pod/server, such as a pXX-buy.itunes.apple.com address. Recently, however, I have encountered all of the following responses:

• 301 Moved Permanently, without a Location header.
• 503 Service Temporarily Unavailable.
• 404 Not Found.
• 204 No Content, with an empty response body.

Some responses include X-XSS-Protection: 1; mode=block, but provide no useful explanation of why authentication failed.

Initially, the same account successfully signed in twice before I enabled a proxy. After enabling it, authentication started failing. I also confirmed that this hostname resolves to different server addresses in different regions. However, the failures now persist, so I cannot confidently attribute the problem to DNS or the proxy alone.

The most frustrating part is that another older iPhone could still sign in initially. After signing out and back in a few times while testing, that device also became unable to sign in and now encounters the same repeated errors.

I have seen similar reports in other communities. This makes me wonder whether Apple has changed something in the authentication backend or its handling of older clients, although I have no confirmation of a policy change.

Could Apple investigate this authentication endpoint and clarify whether App Store sign-in is still supported on iOS 12.5.8? If it is supported, is there a known fix or workaround? It is extremely frustrating to lose access on devices that were successfully signing in shortly before these failures began.

Also getting the same, have tried all the methods, after trying to buy a song and typing in my password which was apparently wrong, led to me also resetting password, clearing the security data in program data, etc etc, going to try reinstalling again, whilst i wait for apple support to get back to me again tomorrow

i've done the date and time thing but it's not that either that's one that messes with DCS World Modules

also have successfully used the phone to purchase stuff and can log in elsewhere

Doing my nut, going to go round in circles again and reinstall itunes though weirdly microsoft store won't allow me to download itunes, so it's back through the website again

what operating system you on? i just tried to log in myself and didn't even get the usual results, though i have yet to restart the pc

edit: restarted pc now i just get "this action could not be completed, please try again"

I have had the same issue since August 13th and have tried uninstall/reinstall both from microsoft store and straight from Itunes site. I have deleted ADI file and made sure the PC clock is automaticlly syncing, and cleared cache in Itunes multiple times. I am wondering if I might be better off using windows media player at this point and buy my music elsewhere. I guess Apple doesn't want us to buy things through them.

I have had the same issue for the last few days and tried countless ways to get it working, and still the log in loop on iTunes and Apple Music for Windows.

I did purchase and log in iTunes store on my iPhone and brought a couple of songs, but no such luck on my Windows PC. Will be keen to know @buddygreat what Apple Support suggest to you and if there will be a release to fix this issue - keep us updated - thanks.

i have the same issue i have tried to delete and reinstall the app and change my password same issue

Thanks for updating us! Hopefully the update on the 9th will fix it, it's been very frustrating.

Same issue here. Do they want to keep customers?

Same issue, just to add context.

Removed and reinstalled Itunes. This worked as recently as early August, exact date unknown.

Apple music works on all other devices. Only issue is Windows Itunes.

Where can I get help with this issue, I can’t get anywhere?
