Much like with normal http, nginx will time out connection to the
upstream server if it doesn't see any data from it. If with a
backend you use there are no data expected from the backend to a
client, there are two possible solutions:

1) Send periodic ping frames from the backend.

2) Configure higher proxy_read_timeout in a location where
websocket connections are handled.
