Oct 18, 2026
Account

The problem
I cannot sign in to the iCloud for Windows app on my new PC. Every attempt fails right after I enter my Apple Account email and password and click Sign In, before any two-factor code prompt appears.
Exact error shown:
Verification Failed — There was an error connecting to the Apple ID server.
The app is the Microsoft Store version: AppleInc.iCloud_13.4.101.0_x86.

What works
My account and password are correct. On this same PC, I can sign in to icloud.com in a web browser with the same Apple Account and see my Photos, Drive, Notes and other data normally. Only the iCloud for Windows app fails.
Troubleshooting already completed
I have worked through Apple Support article 111760 (Resolve issues between iCloud for Windows or iTunes and third-party security software) and more. The error was identical after every step.

No Apple Account outage
Note: “Run as administrator” on the iCloud app could not be tested. Windows blocks it for Microsoft Store apps with “Windows cannot access the specified device, path, or file.”
What I need from Apple
- Check the server-side logs for my Apple Account to see why sign-in attempts from iCloud for Windows are rejected.
- Confirm whether anything on my account blocks Windows sign-in, such as Advanced Data Protection or a security flag.
- Escalate to senior support or engineering if needed, since every standard step has been completed.
I can share screenshots of the error and join a screen-sharing session if that helps.
