ROS bridge on the Amiga ERROR: Unable to communicate with master!

Hi, Farm-NG Team!
In the earlier today, I was able to connect to the ROS bridge.
But after I shout down amiga and restarted it again, I am unable to get access to master.

Please let me know what should I do.
Thank you!

hi! it might be possible that you have to setup again the ROS_MASTER_URI and ROS_IP environment variables.
