I had a working configuration of nginx proxying to an upstream daphne server for django channels. However, when I moved my site to ssl, I started running into issues 403 errors with the websocket requests. This is from my error log:
None - - [24/Apr/2017:02:43:36] "WSCONNECTING /pulse_events" - -
None - - [24/Apr/2017:02:43:36] "WSREJECT /pulse_events" - -
2017/04/24 02:43:37 [info] 465#465: *10 client 69.203.115.135 closed keepalive
connection
And from the access log:
- - [24/Apr/2017:02:48:54 +0000] "GET /pulse_events HTTP/1.1" 403 5 "-" "-"
- - [24/Apr/2017:02:49:03 +0000] "GET /pulse_state/ HTTP/2.0" 200 1376 "-" "Pulse/1 CFNetwork/811.4.18 Darwin/16.1.0"
My nginx config is as follows:
upstream pulse_web_server {
server unix:/home/pulseweb/run/gunicorn.sock fail_timeout=0;
}
upstream pulse_web_sockets {
server unix:/home/pulseweb/run/daphne.sock;
}
map $http_upgrade $connection_upgrade {
default upgrade;
'' close;
}
server {

}
}
This is my requirements.txt:

asgiref==0.14.0
asyncio==3.4.3
autobahn==0.16.0
channels==0.17.2
daphne==0.14.3
Django==1.10
django-extensions==1.7.2
django-webpack-loader==0.3.3
djangorestframework==3.4.4

redis==2.10.5
requests==2.11.0
six==1.10.0
Twisted==16.2.0
txaio==2.5.1
zope.interface==4.2.0
Any insight would be greatly appreciated.
I do have a working configuration for Django+Daphne+nginx+ssl without any issues, I run daphne via supervisor with the following config file:
[program:project]
directory=<project_directory>
command=daphne -u <path_to_socket>/daphne.sock --root-path=<project_directory> <project>.asgi:channel_layer
stdout_logfile = <log_path>
stderr_logfile= <error_log_path>
[program:project_asgi_workers]
command=python <project_directory>/manage.py runworker
stdout_logfile=<log_file_path_2>
stderr_logfile=<log_error_path_2>
process_name=asgi_worker%(process_num)s
numprocs=2
environment=LANG=en_US.UTF-8,LC_ALL=en_US.UTF-8 ; Set UTF-8 as default encoding
autostart=true
autorestart=true
redirect_stderr=true
stopasgroup=true
To stop and start these workers I run the commands:
sudo supervisorctl stop allsudo supervisorctl start allInside nginx I have the following configuration to connect to my websockets:
location /pulse_events/ {
proxy_pass http://unix:<path_to_socket>/daphne.sock;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_redirect off;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Host $server_name;
}
I used on this project daphne version 1.4.1, asgi-redis 1.4.3, redis 2.10.6 and channels 1.1.8.
If you still have issues, maybe it's also a good idea to check your routing and consumers for django channels.
your nginx expects a wss request not a ws request.
I use Django + Daphne + Nginx + SSL and here is my nginx mysite.conf. Your conf file is missed for handling /ws request. And ws and wss will be handle with this parameters. Please be sure you have a backend socket server like Daphne(i see you have), and run this server in bash and accept request in 8443(this is important because most servers permit only in this socket). And enjoy it..
location /ws {
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-for $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_pass http://127.0.0.1:8443;
