nginx + Tomcat 9
Hi,
we are using nginx as proxy for our web app deployed in Tomcat 9.
The app uses websocket. The websocket connection dies after 30/40 seconds and we can't figure out why.
Any suggestions?

Hi, I installed and configured HAProxy as a basic proxy but I'm facing the same issues with my application war:
-when I upload a file > 60k the upload fails (hangs)
-websocket stops working after 30 seconds
Maybe I need to tweak tomcat?

You should go with HAProxy. I have used it in the infra of one of Payment
Gateway..
It works really good.
Let me know.. if I can help you in setting up HAProxy.
Best,

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,

I tried to enable debug logging for org.apache.tomcat.websocket but without success
here is my logging.properties
handlers = java.util.logging.ConsoleHandler
.handlers = 1catalina.org.apache.juli.AsyncFileHandler, java.util.logging.ConsoleHandler
java.util.logging.ConsoleHandler.level = ALL
java.util.logging.ConsoleHandler.formatter = org.apache.juli.OneLineFormatter
org.apache.coyote.http2.level = ALL

- look at the logs ? (of nginx as well as tomcat)
- try to define "dies" a bit more precisely ?
