After installing zeppelin all goes fine, but when you try to connect you may get a "disconnected" status on the notebook tab and you're unable to create any new note, while the interpreter tab works fine.

If you checked you can reach the port on which zeppelin is listen, it may be an issue with your content filter firewall and you should see this log in your firewall application:

2016-02-04 15:47:58 Deny 192.168.0.128 40.112.76.49 http/tcp 57772 9995 1-Ecube 0-Internet ProxyDeny: HTTP Invalid Request-Line Format (TCP-UDP-isoardi OUT-00) HTTP-Client.isoardi proc_id="http-proxy" rc="594" msg_id="1AFF-0005" proxy_act="HTTP-Client.isoardi" line="\x81\x8d\xf2\x9eW\xfe\x89\xbc8\x8e\xd0\xa4u\xae\xbb\xd0\x10\xdc\x8f\x81\x8d\xf8]\xb8z\x83\x7f\xd7\x0a"     Traffic

The solution is to disable the content filter for the domain on which zeppelin is running
