I am trying to obtain a token through postman using the following tutorial:
https://learn.microsoft.com/en-us/azure/healthcare-apis/access-fhir-postman-tutorial
I have successfully filled out the credentials then a pop up appears asking for my credentials. This then throws the following error:

Does anyone know why this error is occurring or how I can fix it?
Thanks
According to your error message: no reply address is registered for the application. So, try to set the callback url for your application, usually the url is the reply address.
Go to AAD>App registrations>your app>Authentication

Please note that the reply url configured in the Azure portal needs to be the same as the url you used in postman.
