Lets just be sure what IP and port you are running on. From a terminal window, enter the following commands:
hostname -I
ps -ef | grep -i ospi
The hostname -I command should return the RPi’s current IP address. Hopefully that is 10.0.1.21 as you expect. It should be recorded in your AE as the Private IP address as you have indicated.
The ps -ef command will look for processes that contain “ospi” in the name or options. It will also return the grep line since ospi is an option to the grep command. Here is a copy of my Pi running those commands:
pi@OSPi ~ $ hostname -I
192.168.1.11
pi@OSPi ~ $ ps -ef | grep -i osPI
root 2401 1 0 18:31 ? 00:00:09 /usr/bin/python /usr/ospi/ospi.py 192.168.1.11:8080
pi 8118 7915 0 21:03 pts/1 00:00:00 grep –color=auto -i osPI
pi@OSPi ~ $
From those commands, you can verify the Pi is doing what you expect it is doing…
Good Luck!
