But i could manage to connect to proxy server.This server provides the port 3128,80,443 for surfing.All the ports are open.But none of then is working for me.They returns the above error code.

If the university is managing the proxy server, you're best off getting in touch with them since there's not a whole lot you'd be able to do to resolve the issue yourself. They could simply have Squid misconfigured or a more serious network connectivity issue, but it doesn't look like it's anything to do with your machine that you could fix.
