Hi,

I am working on C# MVC web application . In this application I am integrating google drive and using Google.Apis (version- 1.19.0.0). For this implementation I have taken the reference from your sample code and have implemented successfully in my application. During testing I have found that it is working fine when I run directly this from visual studio but when I deployed this on IIS (even local IIS) it is not working. After investigation I have found that it is giving problem in authentication and not trigger the authenticate screen with Gmail account. Mainly giving me on this below line :

UserCredential credential = GoogleWebAuthorizationBroker.AuthorizeAsync(new ClientSecrets {ClientId = clientId, ClientSecret = clientSecret} , scopes , userName , CancellationToken.None
, new FileDataStore(folder,true)).Result;

Nothing has happened after this line (no error) . Kindly help me on this . How I can solve this problem? Is there any setting in IIS that I need to set for this ?

Some trouble shooting I already done like :

  1. Given permission to folder (that store the outh response ). Like asp.net users .
  2. Tried with both folder default roaming folder and custom folder (for store the outh response)

Let me know if you want more information from my side.

Best regards,
Sunil Sharma
