Answer 1

Thanks for the reply Jkbull .
My issue was solved by using "Viscosity" a vpn client for Mac which even works with OSX Yosemite.
but i cannot find any solution for tunnelblick.
I am not sure but think the problem was with tun-tap settings or 443 port.
I have tried changing the reference to "pun-in.earthvpn.com" in the OpenVPN configuration file to its current IP address of "103.250.184.251".
I have an option in mac network settings to use one or more DNS Servers so i have added Google Public DNS and my college DNS server- "202.141.81.2".
I Cannot connect to Internet by not using proxy because our connections go through our proxy server "202.141.80.19:3128" and we have user-password login for this server to establish a internet connection.
The Problem still persists.
When i connect with viscosity,
Initially i use my college proxy settings.
Connect to EarthVpn by using Viscosity
It asks me with the username, password of the earthvpn account and when provided it establishes  connection.
I use no proxy(that is remove my proxy settings) after the connection is established.
Now it is connected to VPN.
I wish tunnelblick guys come up a solution for this problem.
