Sign in with Microsoft on minecraft.net not working

When pressing the “Sign in with Microsoft” button on https://www.minecraft.net/en-us/login , you get redirected to https://www.minecraft.net/en-us/login?error=unauthorized_client&error_description=The%2Bclient%2Bdoes%2Bnot%2Bhave%2Ba%2Bsecret%2Bconfigured.%2BIf%2Byou%2Bare%2Bthe%2Bclient%2Bapplication%2Bdeveloper%252c%2Bconfigure%2Ba%2Bsecret%2Bthrough%2Bthe%2Bapplication%2Bmanagement%2Bsite%2Bat%2Bhttps%253a%252f%252fgo.microsoft.com%252ffwlink%252f%253flinkid%253d2083908.#state=login.

Decoding the part after error_description= produces the following message:

The client does not have a secret configured. If you are the client application developer, configure a secret through the application management site at The client does not have a secret configured. If you are the client application developer, configure a secret through the application management site at https://go.microsoft.com/fwlink/?linkid=2083908.#state=login

Note: There have already been multiple people (at least 5) on the Minecraft Discord reporting this issue, so I assume its not just me having this exact problem.
