B2C redirect url issue with LB

Question

Hi @AmanpreetSingh-MSFT

Need you suggestion on following scenario:

b2c user login, redirect, sign out everything works fine if I host my app as public facing (i.e. deploy as webapp which can be accessed through plain internet) and It also work fine with localhost redirect.

But if deploy this app on VM inside private vnet I am unable to sign into user through b2c login screen. There is no error and it just reloads same page and user has not signed in. I have reply url and redirect url in config file)as internal LB with valid certificate.

As per my understanding there is no such requirement that app must be hosted as public facing when redirect from b2c registered app.

Is there any network requirement when redirecting from b2c after successful login? Can you please help me understand any other troubleshooting step here?

Thanks,
Vikas Tiwari

Hi @Vikas Tiwari · Yes, it is not required that the app must be hosted as public facing and there are no specific network requirements when redirecting from b2c after successful login.

The issue could be due to LB, as some load balancers do SSL offloading. LB logs should contain more details.

You can also avoid using LB by using WAP (Web Application Proxy) or Azure App Proxy to expose the application (hosted on the internal server) to internet.
