Hello I'm facing this issue on daphne 3.0.1 :

If i get everything back to old version it works again using old channels code & files.
channels==2.4.0
daphne==2.5.0
channels-redis==2.4.1

Things i tried so far :

• Removing all old daphne versions.

• Installing daphne using a superuser session.

• Changing the order of installed apps on settings.py.

• Running daphne without -u .sock.

• Tested AuthMiddleware instead of my custom SimpleJwtTokenAuthMiddleware in asgi.py + testing without Auths.

• Running daphne command line directly on django folder.

And nothing seems to work so far.

Also same error on local running just : daphne demo_API.asgi:application

Details :

Any help or suggestions will be apreciated.

Hi @Altroo.

See the updated deployment docs here:

https://channels.readthedocs.io/en/stable/deploying.html#configuring-the-asgi-application

I think the issue will be the JWT auth middleware. Looks like it's accessing the user model before this line:

django_asgi_app = get_asgi_application()

I'd say that if you move that import below there it should work.

Worked for me too.
Thank you. Spent 2 days on this before reaching to your post.

Can't thank you enough man. I read through this document but somehow missed that! Thanks for pointing it out. Spent all day on this problem. Problem solved. Though seems like my media files aren't loading anymore. i will find out why.

Meanwhile I am just happy the server is back up!

Very thanks man!!! I missed completely that documentation part

I was stuck on this for 2 days until I found this post. In my case, Visual Studio Code auto-formatter did the bulk of the work for me and re-arranged my imports, making the get_asgi_application() be down the line.

[elohmeier]

Another tip: you can add "# isort: skip_file" to the beginning of your asgi.py to prevent isort from reordering automatically.

This just saved me. Thank you so much.
