@Thomas Letourneur , Thank you for reaching out. The error "AADSTS50011: The reply URL specified in the request does not match the reply URLs configured for the application:" would come up when there is a mismatch of redirect URI being sent in the request to AAD while fetching the token and the one registered with the Application Registration Object in AAD portal.
In your case you need to check the redirect uris configured for the following application ID 4c9f8d57-3372-47b8-9f05-067a5127b9e4 registered under the Application Registration blade of AAD and look for the redirect URI section present under "Authentication" section of the registered application. Please refer to the screenshot below:
Hope this helps.
