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](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 ([Module ngx\_http\_proxy\_module](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.
