Too many redirect daphne, nginx,django channel ubuntu 20

[halhwadi]

My site is working properly but the issue right now is redirecting http to https, I tried to configure the nginx but every time I get "Too many redirect" eorr, i have clear the cache but with no luck

when I add return 301 https://$server_name$request_uri; or rewrite command to server block I got Too many redirect error, I tried to comment this line proxy_pass http://channels-backend when adding the redirect but does not help...

You want the redirect only if the protocol is http. This is an NGINX question. I'd try Server Fault for help.

Thanks for your reply and assistance
Yes it has nothing with Daphne..

Issue has been solved by:
1- adding protocol header to nginx:
proxy_set_header X-Forwarded-Proto $scheme;

2- Adding the following lines to setting.py file:
SECURE_SSL_REDIRECT = True
SECURE_PROXY_SSL_HEADER = ('HTTP_X_FORWARDED_PROTO', 'https')

Third point is adding --proxy-headers to daphne run command in sock file; but not sure if it has any affect on sharing protocol with Django

Best Regards

it is not working for me when i used --proxy-headers it is not passing x-forwarded-proto.
my django application is getting http instead of https in x-forwarded-proto

i have found the solution of my problem.

The problem was with cloudflare. i had proxied enabled in cloudflare because of which i was getting request from an ip instead of a domain and wrong nginx config was being used.

I just disabled proxied in CloudFlare DNS record and it worked.
