I'm using eclipse 4.6.3 with Force.com IDE 18.104.22.168701101558. When I enter my credentials in project properties it says
com.salesforce.ide.core.remote.ForceConnectionException: Unable to create connection to server 'test.salesforce.com': SocketException: Unexpected end of file from server at com.salesforce.ide.core.internal.utils.ForceExceptionUtils.handleConnectionException(ForceExceptionUtils.java:74)
It is a sandbox environment and I have that option selected in project properties. I'm able to get an OAuth token from test.salesforce.com with the same credentials from the same laptop and IP address. I don't see any login attempts in login history when I try to connect. One of my coworkers has the same versions and is able to connect to salesforce. I've also tried downgrading to eclipse 4.5.2 and had the same problem. I'm using
to download the plugin. Does anyone have an idea why this could be happening?
