Recently we were facing an issue in client place is that we were unable to communicate to web service even we checked that there is no system proxy set in that system, to overcome this we had given a dummy proxy (localhost:port) and its started working well but after some days with dummy proxy it was unable to communicate to service if we remove dummy proxy then it started working well. i am not able to understand what is blocking me to communicate to service. what may be the issue and how can we overcome this problem. This issue is happening only on some system.
Actually it has to go and hit this URL http://********-tech.in:8080/******dp/ClientVersion but suddenly it started hitting this one 125.21.244.38:8080 why i am not able to conclude.
