The client ID in your sign-in request doesn’t exist in the tenant you’re authenticating against.
Exact message you may see

Azure
Meaning
Either the app ID is wrong, the app is registered in a different tenant, or a multi-tenant app hasn’t been consented in the user’s tenant.
Common causes
- Wrong client/application ID
- Using a tenant-specific authority for a different tenant
- Single-tenant app used by external users
- App registration deleted
⚡ Quick fix
- Verify the Application (client) ID in Entra ID → App registrations
- Use the right authority (
/common,/organizationsor the tenant ID) - Make the app multi-tenant if external users sign in
