Cannot searching from google scholar

[couragelfyang]

JabRef version 3.4 on Arch Linux 4.5.4

Steps to reproduce:

1. I get nothing through searching feature from google scholar, there is "status: searching" displaying on status bar all the time. But I can achieve expected results with JabRef 3.4 on Windows 7.

Thanks for the detailed error message.
A SocketException indicates that the Remote host (Google) unexpectedly closed the connection.
Is this reproducible, e.g. does it happen every time?
Do you use a Proxy?

[couragelfyang]

It happen every time and I use shadowsocks.

@AriaAsuka There we see the reason HTTP code 403 -Forbidden. So this is not a Problem of JabRef.
Seems like Google Scholar has blocked your Proxy-IP.
A quick Google Search turned up with this, maybe that helps you:

The only improvement we can do in JabRef is do display a more clear Error message
