Question

AADB2C: OpenIdConnectConfigurationRetriever() gets an IDX20807 exception

Carol Lai 526

This code used to work, but now we are receiving IDX20807 exception when running from our local machine. It does work on App Service.

string stsDiscoveryEndpoint = $"https://{domain}.b2clogin.com/{domain}.onmicrosoft.com/{policy}/v2.0/.well-known/openid-configuration";

I changed it to use TLS1.2 and it's now working.
