invalid_request: The provided value for the input parameter 'redirect_uri' is not valid. The expected value is a URI which matches a redirect URI registered for this client application.

hi i have the same error for microsoft rewards i am attaching the screenshot below

We're now in Day 2 and no solution or response forthcoming. For the record, here are the two ways I've tried to access the Microsoft Rewards dashboard with the same "Invalid request" result:

1. Use a link in my bookmarks that has worked until yesterday. ---> Invalid request
2. Login to Microsoft via Outlook website.

Go to bing.com website.

Click the rewards point total at top of page.

Click the "View dashboard" link at top of drop-down. ---> Invalid request

3. Type "account.microsoft.com/rewards" into address bar and hit Enter. ---> Invalid request

The problem seems to be specific to Google Chrome. Don't see the same problem with Firefox or Edge (Chrome lite).

FWIW --- I'm using a Mac, not Windows.

Using Microsoft Edge here; even switched devices to try and get the rewards page to work. No luck on my end either after 4 days in!

Tried using a bookmarked page, as you did, and still didn't work.

invalid_request: The provided value for the input parameter 'redirect_uri' is not valid. The expected value is a URI which matches a redirect URI registered for this client application.

FYI - I'm on Windows and this is still happening to myself and others around me

I also have this message when I try to open it, if I go to the microsoft rewards website it looks normal, but if i click "log in" it comes with that message, same goes with "registration".

For me it's the other way around. I get this error in edge, but not in chrome.

i have the problem with Edge, i didn't try another one, i'll check firefox
