internal server error 500

[hugo]

after starting the web server it throws an 500 error

pi@raspberrypi:~/phatsniffer $ ./server.py 
 * Running on http://0.0.0.0:5000/
192.168.178.20 - - [29/Aug/2017 15:49:38] "GET / HTTP/1.1" 500 -
192.168.178.20 - - [29/Aug/2017 15:49:38] "GET /favicon.ico HTTP/1.1" 404 -

any tips on how to setup logging or debugging this issue?

[Lars Juhl Jensen]

Look at the last line in the script: change debug=False to debug=True to get Flask to output debug information.
