Forum: NGINX WebSockets - connection keeps closing after 1 minute

Hello!

My WebSocket connections keep closing after precisely one minute.
The configuration is the same as provided in that commit comment.
http://trac.nginx.org/nginx/changeset/5073/nginx

Direct connections to the server (without intermediate nginx) happily 
live
for many hours.

What option should I change to fix that?

There is proxy_read_timeout (http://nginx.org/r/proxy_read_timeout)
which as well applies to WebSocket connections.  You have to bump
it if your backend do not send anything for a long time.
Alternatively, you may configure your backend to send websocket
ping frames periodically to reset the timeout (and check if the
connection is still alive).

Thanks, raising the timeout resolved the problem.
