Hi,
I’ve configured HA Proxy as the load balancer for a couple of Symantec proxies on the back end. Generally everything is working correctly, but I’m intermittently seeing issues with some websites. One being Twitter and the other one What’s App.
Looking at Twitter, when not working, the following URL does not load, https://twitter.com/push_service_worker.js, but displays a 503 error. Whether the site loads or not, I’m seeing exactly the same request headers, see attached.
If I point the browser to any of the proxy servers on the back-end directly, this error does not occur. I’ve verified this with multiple browsers.
Just wondering what else I can do to trace what is happening here? A basic tcpdump on the haproxy server, shows the request does reach the load balancer.
Thanks for any help.
