I've been trying to run robot_state_publisher and joint_state_publisher on a remote TX1 running Ubuntu 16.04 and ROS Kinetic. When running the node from a local launch file (manually ssh into the remote machine and run launch file), everything runs fine. However, when I try to run a launch file from my local machine, I get this error in my terminal:
[192.168.1.237-0]: [robot_state_publisher-28] process has died [pid 26798, exit code 255, cmd /opt/ros/kinetic/lib/robot_state_publisher/state_publisher __name:=robot_state_publisher log:=/home/nvidia/.ros/log/038bfbd8-7afb-11e8-b9f2-ac220b57ae89/robot_state_publisher-28.log].

How can I fix this?
Here's my launch file:
jsp = JointStatePublisher()
