One of our legacy applications is using Apache Commons HttpClient 3.1. POST call to one REST service is failing with "java.net.ConnectException: Connection timed out: connect" exception[1]. Timeout is occurring after one minute. To figure out where thread is spending all the time, I took multiple thread dumps. In all of them, thread is trying to create secure socket[2]. I am not seeing any thread pool issue. Also the target REST service is working properly with same payload while invoked from Postman. It is only failing consistently when going through the HttpClient. I am trying to figure out why it is taking so long in connecting to the socket. I am looking for suggestion on how to attack this one.
