This method RequestClientCredentialsTokenAsync to generate token (oauth2) works fine for me when I call it from unit test, but from the API MVC .Net Framework 4.6.1 I have this exception : ( I am sorry, the exception is in french language)

    No problem, please translate error to English. – zsolt Mar 06 '20 at 20:04
  • A connection attempt failed because the connected party did not respond properly beyond a certain time, or an established connection failed because the connection host did not respond 171.18.28.75:443 System.Net.

  • keep in your mind that the same method works for me when i call it from unit test o.O – Firas Farhat Mar 06 '20 at 20:27
  • It looks like a network connection error. Do you use appropriate connection parameters (url, clientid, secret etc) ? – zsolt Mar 06 '20 at 20:31
  • yes, the parameters used in the unit test are the same also used with the API framework – Firas Farhat Mar 06 '20 at 20:35
  • tokenResponse.Result contains this error : HttpErrorReason = {"The object reference is not defined to an instance of an object."}, ExpiresIn = 0, Exception = {"An error occurred while sending the request. "} IdentityModel.Client.TokenResponse – Firas Farhat Mar 06 '20 at 20:40
  • just guessing, is authenticationToken instantiated and does it have good value? – zsolt Mar 06 '20 at 21:10
  • I have a good value for the auithenticationToken but always i have the same exception. like i said, this function work very well when i call it from unit test, i guess that i have problem with identityModel and web api framework 4.6.1.. – Firas Farhat Mar 07 '20 at 17:07
