Can FTP to robot, Netbeans can't
 
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:

Re: Can FTP to robot, Netbeans can't
 
There are two things to look at:

1) The output said:
Quote:
Remote OTA server does not match, upgrading
Which might implies that something changed. So is this the first time you've used that development machine on that cRIO? Or are using a new version of the netbeans modules?


2)

Double check the windows fire wall. The SDK uses a java implementation of an ftp client, so the Java executable needs permission to open ports, etc.

Re: Can FTP to robot, Netbeans can't
 
I tired it running as an administrator with the Windows Firewall completely disabled (nothing but the robot on the network). Still the same error.

I hadn't noticed the remote OTA message. I usually associate that with the cRIO being reimaged. It was reimaged, but it has been working since then. The only thing I changed was networking settings (specifically HomeGroup settings) on the other network interface. Even with that network interface disabled (as it was in the output you see above), it still doesn't work. I've tried another computer as well and I've double and triple checked the network settings:

Computer IP: 10.6.19.6
Subnet: 255.0.0.0

I'm going to try reimaging the cRIO now.

No luck with reimaging. Or rather it reimaged just fine, but the problem persists. It works just fine with a wireless connection, by the way.
