Hello, we are having issues with the push integration for Android. We have two installations of 3CX at different sites, both have the issue. I have followed the guide and set it up through Google APIs etc and seems to be working on that front, but the issue I am seeing in the 3CXDialier logs is the following: 16/06/01 14:04:10.285|200001| Err|10|0017|: *!* Exception catched at Android Push sender: System.Net.WebException: The remote server returned an error: (407) Proxy Authentication Required. at System.Net.HttpWebRequest.GetRequestStream(TransportContext& context) at System.Net.HttpWebRequest.GetRequestStream() at Dialer.PushClient.PushAndroid(CallData c, Int32 reason) We do have a proxy server and I have specified that both systems bypass this, but it appears to be detected and is blocking it. I assumed the only way around was to allow the address through for Google Cloud Messaging (https://android.googleapis.com/gcm/send), but it hasn't made a difference from what I can see. Anyone had this issue before? Is there a different address that needs unblocking or an area I can specify proxy details? Thanks!
