...machine cannot connect to itself.
Distro: melodic Platform: Jetson Nano Linux: Ubuntu 18.04.6 LTS (bionic)
I am perpetually getting error: "Unable to contact my own server at [http://192.168.0.27:35913/]. " .... " A common cause is that the machine cannot connect to itself. " when I either try to launch a new package or even run roscore.
Regularly when I started up the Jetson it was issued with a new IP number by the local DHCP. I have now set both eth0 and wlan0 to static IPs, however this has not sorted out the problem.
I assume that this problem is associated with environmental variables, but I understand that it is inadvisable to adjust them manually. I have tried: source /opt/ros/melodic/setup.bash which I thought would reset the variables including the IP number, but: export | grep ROS still produces: ROS_IP="192.168.0.27" ... not the current static IP.
I would much appreciate any help on this.
