I'm getting this error below, any ideas? Thanks!

No connection could be made because the target machine actively refused it 50.18.179.4:443

Exception thrown from line 127 in refreshToken() method in ET_Client.cs.

string json;
using (var streamWriter = new StreamWriter( request.GetRequestStream() )) {

Networking guys said it isn't connection through proxy and should be.

I don't believe your error is related to the SDK. These may help:

  • It was issue with how our internal network handles SSL connections. Running Fiddler fixed the issue. – Gerard Feb 24 '15 at 3:29
  • OK, so when I connect from outside my company network, I'm able to get the connection. So this brings us to the next question. Am I able to configure a proxy in FuelSdk or do I need a firewall hole? If a firewall hole, what port? – Gerard Mar 3 '15 at 6:25
  • Can you post the line of code receiving this error so we can see what you're doing? – Drew Simmons Mar 3 '15 at 14:19
  • added code, think HttpWebRequest request needs to use corporate proxy. – Gerard Mar 4 '15 at 23:37
