When trying to run the example chat server I get the following error

(django_test)[xxx@yyy examples]$ python manage.py runserver 0.0.0.0:8000
Performing system checks...

Then there is an endless loop of failed websocket connections, What may be hapenning here?

This seems weird:

[2016-09-14 13:28:38,721 websocket] INFO: websocket.receive: WebSocketError Unexpected EOF while decoding header

which browser? any firewall/proxy in between?

Chrome Version 52.0.2743.116 m (64-bit) and no firewall / proxy in between but a VPN

@jrief i see this as well however only see this on safari client 10.0.1 (11602.2.14.0.7). Chrome 54.0.2840.98 and Firefox 47.0 work fine. Its definitely browser dependent. Looks like something in safari's latest 10.0.1 rollout broke this client.

Hello guys.
I have the same errors on my console:

websocket.receive: WebSocketError Unexpected EOF while decoding header
INFO 2022-06-23 11:15:40,460 [django.request:websocket.py:222] [Thread-19] websocket.receive: WebSocketError Unexpected EOF while decoding header

What I found during debugging.
For now, I have to disable WS4REDIS_HEARTBEAT and in this case, the issue is present, but...
When it is enabled there are no issues.

Can it be helpful to resolve this issue?
