Subject Re: nginx + Tomcat 9
Date Fri, 13 Jul 2018 14:13:39 GMT
Hi Simon, 

I only get oputput in logs with nginx debug, but it is way too much verbose and I can't determine
why the connection times out. 

I get no useful messages in tomcat logs neither. 

I think I'll set up and HAProxy test environment and see how it works with my app and tomcat.


I suspect I need the nginx+ payment options/support. I'm happy to pay but I've read about
HAProxy vs nginx and it may be better fitting my needs; so it's worth the test.

I had a similar problem. I could resolved it by sending a keep alive 
message from the browser. 
If you still get disconnections (backend or middlerware could disconnect), 
you need some logic in the frontend to restart the connection. 
I didn't have to change any tomcat configuration, or the websocket code. 

You can test connecting direct to tomcat websocket (without nginx) to check 
where is the problem. 
You can also read these nginx configs: 
proxy_connect_timeout 
proxy_read_timeout 

Hope it helps,
