django heroku when debug is false and allowed host is set i get still a 500 page - how i have to set my settings that i come to my Startpage

Question

i load a new app to heroku and then i made a customer domain www.mydomain.de. if i let in my settings.py the DEBUG on TRUE everything work fine, but in production thats not so good. if debug is flase and i set the ALLOWED_HOSTS = ['.myDomain.de'] but i get then a 500 page. Why? (see in my code) So how i have to change my settings.py or heroku that the page work. Thank you for your help!

Heroku does not support djangos default static file serving in production. Please see the Heroku Docs: Django and Static Assets on how to change your settings.py. Also have a eye on this subtopic Django Assets: Collectstatic during builds.
