Hi @Kieran Larkin · Thank you for reaching out.
The error occurs when reply url in authentication request doesn't match with reply url(s) registered in the application.
Reply url specified in the authentication request is https://login.microsoftonline.com/common/oauth2/nativeclient
Reply urls registered in the application 'eecff9c5-xxxx-xxxx-xxxx-b1e03387615b' are:
- https://db3--exxxxxxxxxx617.crm4.dynamics.com/oauth2/authresp
- https://sxxxxxxltd.crm4.dynamics.com/skillnet.onmicrosoft.com/oauth2/authresp
To resolve the issue, update the reply url registered in the application to match with the one in authentication request by navigating to:
Azure Portal > Azure AD > App Registrations > Search the application by using App ID > open the app and click on authentication blade > update the redirect uri.
