Method works as expected on host machine but not on server

Look if 'traffic_light.ini' are locally and on the server are identical.

Did double check that, they are identical.
I also noticed by reading the docs that configparser does expect strings to be wrapped in commas, so I removed them in traffic_sign.ini.
Yet, still the same undesired behaviour.
It seems like the constant doesn't get updated during the while loop and stays the same than at the beginning, but I can't figure out why.
