Can FTP to robot, Netbeans can't

[computerish]

Earlier today I was able to download and run code on the robot with no problems. Netbeans suddenly stopped being able to connect to the robot, though. I can still ping both the router (on the robot) and the cRIO. I can also FTP to the cRIO with FileZilla. This is the Netbeans output:
