Eclipse won't connect to roboRIO

[TheMechanic40]

My team, 3506, has been using netbeans to upload to code to our robots in previous years, however the roboRIO no longer supports plugins for netbeans and my team has had to switch to using eclipse. We code our robots in Java and after going through the long process of setting up the roboRIO for Java attempted to upload some code. Here's the problem: three of the six people on my programming team can upload code to it (two using roboRIO-3506.local and one using 10.35.6.2), but the rest of can't. The three of us that can't upload code can ping the roborio at both addresses and consistently get replies, but whenever we try to upload code from eclipse we all get the same error message: roboRIO not found, please check that the roboRIO is connected, imaged and that the team number is set properly in Eclipse. Our team numbers are all properly set, and we know that it is properly imaged and connected because the others can upload code and we can ping it. Does anyone have any possible solutions?
