Upstream Web Proxy settings

[deleted-user-XuM8YOt_1Aqt]

Hi,

I have an issue trying to get EM4C to communicate with our Organization account via our internal web proxy. 

I get the following HTTP 407 response in the cgiError log. 

Curl Error(56):
   Failure when receiving data from the peer
   Received HTTP code 407 from proxy after CONNECT

Our proxy requires NTML and its possible this is error occurs when basic authentication is used.  Is it possible to specify NTLM authentication for the upstream proxy?  The documentation details how to set the proxy URL but no further configuration. 

Thanks
Aidan
