Internal Server Error

[hnoguchi]

I modified server.py → " mon = co2.CO2monitor(bypass_decrypt=True) ", then it works.

I have followed the setup instructions, but when I could not access the CO2monitor dashboard as below.
Any help would be much appreciated.

pi@raspberrypi:~ $ co2meter_server -H 0.0.0.0 -P 1201
