how to fix redirect uri not valid?

Question

Im trying to log into my account for a website which requires connection to my microsoft account (mcdstuff if thats relevant) but when i try to sign in i recieve this message "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." does anyone know how to fix this becuase i need to use this website for my work. I have tried looking for answers to do with redirect_uri problems but they are all to do with people coding or using something called microsoft azure which i havent heard of and i dont think my problem is to do with that. Any help would be greatly appreciated as im really stressing out here. Thank you!

If you are getting that error on a website you do not own or have the ability to change, you need to report the bug to the admins for that site. They need to fix their redirect URI in Azure or in their code and make sure that it matches. You could reach out to @McDonalds on Twitter and report this issue.

It does look like their website is having issues because I tried to go to the "Help" page and got an ERR_CONNECTION_TIMED_OUT

You can try logging in using an incognito/private window to see if you get a different response, but the reply URL error means that they have a mismatched or incorrectly formatted reply URL configured on their end.
