rviz: cannot connect to X server, [rviz-1] process has died [pid 28659, exit code 1

edit

hello,I am doing the experiment with the Husky UGV robot, I suddenly encountered a problem that I've never experienced before. I've also tried the solutions provided in the community such as add the ssh -X, to address this problem, but it still persists.

My robot computer and remote computer are both running Ubuntu 14.04 and ROS Indigo. Now, I connect to the robot computer using ssh administrator@hostname from the remote computer, and then run the navigation package and then run the roslaunch husky_viz view_robot.launch. However, I encounter an error as described as the title.

the issue log as the fellowing:
