SharePoint Online Add-in throwing AADSTS50011

Question

I have a couple of Sharepoint Add-in (Sharepoint hosted) that have been working perfectly till 2 days ago! Now return the following error: I get the following message: AADSTS50011: The redirect URI 'https://[mycompanyname].sharepoint.com/_forms/default.aspx' specified in the request does not match the redirect URIs configured for the application '00000003-0000-0ff1-ce00-000000000000'. Make sure the redirect URI sent in the request matches one added to your application in the Azure portal. As this is a Sharepoint Add-in I can't see any on azure, and I haven't made any changes. I found that some people have this error and it was resolved on the 28-29 Jan 2024, but I am still facing the issue, and the clients are not happy.

Hi @Luis Lerones, Check for the Authentication request in the address bar of the Microsoft login page. See if that redirect_uri matches with the reply_uri/redirect url in Azure AD (Sign into portal.azure.com => Navigate to Azure Active Directory in the left side bar > App registrations > Your app > Authentication > Redirect URIs.). Try to check the redirect uri where you configured in your Web api (ex: App settings.json or in conrollers or views) Here is the document for this issue, please make a reference https://learn.microsoft.com/en-us/troubleshoot/azure/active-directory/error-code-aadsts50011-redirect-uri-mismatch

This is still an issue. We experience this issue only on updated and new Add-ins. Older add-ins are still fine for now.

Has anyone has a solution?
