Also I observed when, I am trying to run application using JRE 1.8.172 same code work fine. In windows JRE 1.8.192 also working.
I also added mydomain.com in my DNS. and mydomain.com certificate in my code.
Few Links:-

https://confluence.atlassian.com/jirakb/java-security-cert-certificateexception-no-subject-alternative-dns-name-matching-hostname-found-297669411.html
There has been a change in Java 8 update 181 and later with the default settings in JNDI when a client connects to a server using SSL. If the server's certificate hostname doesn't match the host that the client connected to, the connection is rejected with that exact message.
The issue and the workaround are described in the Java 8 update 181 release notes.

java.net.ConnectException: Connection timed out: connect when we download java client application from Java web Start

Our Java Client Appllication(Java Swing Application) is downloaded by java web start.At that time its throw following exception.
I have following questions.
What is reason for this exception?
is this because of client code or Firewall(windows and internet)?
If I set java control panel->Network settings and check direct connection its working fine. if its "use browser setting" this exception fired.But some machines with "use browser setting" its working fine.
Does anyone have any idea?
