Unable to obtain configuration from Azure AD B2C

Following this tutorial by Microsoft, the JavaScript application is not able to access the API protected by Azure AD B2C. The application is able to login/authenticate, but when clicking the Call Web API button, the following message is output onto the page:

Web APi returned:
"AuthenticationFailed: IDX10803: Unable to obtain configuration from: 'https://b2c-tenant-name.microsoftonline.com/tfp/b2c-tenant-name.onmicrosoft.com/B2C_1_signupsignin/v2.0/.well-known/openid-configuration'."

How can this be repaired? What change is required to allow the JavaScript SPA to call the protected web API?

Well that URL looks a bit odd. It should be something like:

https://b2c-tenant-name.b2clogin.com/b2c-tenant-name.onmicrosoft.com/v2.0/.well-known/openid-configuration?p=B2C_1_signupsignin

I got this from the Run user flow feature in the Azure portal.

You can't use microsoftonline.com URLs any more. They were deprecated. The host is now b2clogin.com.
