have you googled your error and tried any of the dozens of suggestions for troubleshooting this on your own? — Jason, Apr 11 '17 at 20:35
`System.Net.Sockets.SocketException: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond` this line has me thinking it might be a firewall issue. And also what Jason mentioned. There is a ton of help on this out there. — Gerald Versluis, Apr 12 '17 at 06:11
I have googled it a lot by this error message, "System.Net.Sockets.SocketException: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond" but it gives me links for asp.net and not for xamarin.ios or Xamarin.Mac stuff. I could not find suitable solution that's why posted it here again. I would highly appreciate if you can provide me with some useful link. Thanks :) — Ali Raza, Apr 12 '17 at 06:37
@AliRaza did you figure out the issue? What did you do to fix it? — Euridice01, Apr 28 '17 at 15:25
Yes, I have figured it out. The problem was with virtual machine settings. IT was set to biased connection. I changed it to NAT mode which worked for me. — Ali Raza, May 14 '17 at 13:23

I know its sort of late but troubleshooting this issue is very simple with these easy steps

Check that your mac agent is not locked and not in sleeping state.
Go to your mac agents section.
Disconnect and then reconnect to your mac agent.
Deploy your app after making sure of Point 1.

In case of any queries revert!
