Getting : ERROR: Exception in request: java.net.SocketException: Connect

HI  I am having the same issue, I have to hit the endpoint 3-4 times in ReadyAPI in order to get a successful response. However, if I use the actual UI (Mobile app) to hit the exact same endpoint it works every time.  (i.e service automation fails but UI automation pass for the same endpoint).   We are using hostname and not an IP , Thus the solution provided here don't fix the issue. We are using  Licensed ReadyAPI 3.3.0 .
