301 redirect on Heroku

Works great locally with runserver or heroku local (uses procfile/daphne) but on heroku I receive nothing but 301’s at any endpoint until the browser cancels the request (except for preflight OPTIONS):

I also faced with that problem. Locally I use django with SECURE_SSL_REDIRECT=False, but in remote env I use SECURE_SSL_REDIRECT=True. Daphne do not forward headers to django by default, and django always get http and respond with redirect to https.

Running daphne with --proxy-headers params solved my problem.

Do you plan to make documentation for daphne with more usage examples?

I’m afraid we can’t help with problems that only occur on Heroku - you’ll need to ask their support channels/forums instead. Sorry!
