ssh connection hangs with 'SSH2_MSG_KEXINIT sent'

I am trying to connect a remote machine(running Ubuntu-14.04 ) with ssh, but the connection hangs.
Here is the client log

I tried to increase the MTU, by reading this https://bbs.archlinux.org/viewtopic.php?id=186352 but that didn't help.

Both client and server are in the same subnet, both have usual eth0 interfaces, where ssh works fine.
This problem arises when I put both machines to same vpn and try to ssh.

Re: ssh connection hangs with 'SSH2_MSG_KEXINIT sent'

Can anyone give me hint that is it client side issue or server side ?

One more observation!
It works well when using wifi instead of wireless connection
