Cant change apple id password - Unexpected HTTP response: undefined undefined

Hey there WebDevGuy,

Thanks for reaching out to Apple Support Communities. We're happy to provide some assistance.

To help isolate this issue, are you able to try a different browser? If the issue occurs with another browser, try a different device. Take a look here on how you can change your Apple ID password on different devices:

Have a great day!

I found the same issue happening when I went to Change Password on Windows 11 using Google Chrome.

I looked at Chrome Developer Tools when on the Change Password and could see a few JavaScript errors that related to React, one other interesting error was related to a Content Security Policy violation, I wonder if a Chrome add-on as trying to inject code into the website DOM and causing issues, because it referenced an inline script which Apple doesn't allow per it's Content Security Policy HTTP header.

Edit: It appeared to be Vue Dev Tools which was causing the Content Security Policy error as it had the setting of run on all sites. It however isn't the cause of the error as it still happens.

For me I went on incognito mode and it was OK, so I can only assume something within my Google Chrome profile was interfering.

I would try another browser as suggested to rule it out.

I had the issue. What I found was that there was a special character that AppleID did not like. Once I created a

different password - the issue was corrected.
