active-directory-b2c-xamarin-native: [UWP] Login via OpenId Connect IdentityProvider - We can't connect to the service you need right now. Check your network connection or try this again later.

Hello,

I have already implemented your sample into an external app, but i got errors while login with an openid identity provider.

To reproduce this problem I checked out your latest master, tried to reproduce this error within your solution and it also occurs there. I just changed the B2CConstants file values and everything is working for local accounts. In my Azure B2C I have created 2 identity providers for different AD’s in my signin/signup policy.

For Android and iOS everything works fine as expected, also the login with the identity provider. If I log in with the UWP App via the identity provider i get the following error:

In my external app, sometimes its possible to login via the identity provider if I first login with local account ⇒ logout and login again with identity provider credentials. But its not really a workaround because the error comes again on the next login.

I configured the identity provider with following documentation:

https://docs.microsoft.com/de-de/azure/active-directory-b2c/tutorial-add-identity-providers

I tried following things:

add Capabilities:

<Capabilities>
<Capability Name="internetClient" />
<uap:Capability Name="enterpriseAuthentication"/>
<Capability Name="privateNetworkClientServer"/>
<uap:Capability Name="sharedUserCertificates"/>
<uap:Capability Name="userAccountInformation"/>
<Capability Name="internetClientServer"/>
</Capabilities>

found it here: https://github.com/Azure-Samples/active-directory-b2c-xamarin-native/issues/137

And tried also setting the registry and redirect url which is created from the app during execution: https://github.com/AzureAD/microsoft-authentication-library-for-dotnet/wiki/UWP-specifics#properties-of-platformparameter-specific-to-winrt-and-uwp-corporate-network

Im not quite sure what im missing or doing wrong, hope you can help me.

Thank you!

/edit Maybe some additional information, I developed the identity provider login with a signIn/signUp (default) policy, that was working at the beginning, the error occurs only sometimes. After I changed to a only signin (default) policy, the error occurs nearly every time (only works with the workaround which i described already).
