What is "java.net.NoRouteToHostException: Cannot assign requested address"?

Question

That's it. I have never seen before. I am trying Tcp Holepunching.

One Client should be both client and server(for other client).

I got this Exception. Is there anyone who know about this problem?

java.net.NoRouteToHostException: Cannot assign requested address

    at java.net.AbstractPlainSocketImpl.doConnect(AbstractPlainSocketImpl.java:339)

Where is the code that should accompany this question? – user207421 Aug 03 '16 at 04:54 — user207421, Aug 03 '16 at 04:54

hey can you check you request is use keep-Alive option? If you are doing a stress test, please try turning it off.

Signals that an error occurred while attempting to connect a socket to a remote address and port. Typically, the remote host cannot be reached because of an intervening firewall, or if an intermediate router is down. Read this Documnet
