Getting a 503 only when using f5
Hi, 503 is application gateway. Probably not related.
I've had cases with BI tools that download java to the client.
The java app then establishes a secondary connection that is not associated with the browser. See if java is running..
To debug this you will need to capture the traffic.
Set up SSLKEYLOGFILE

Setup wireshark to capture port 443, clear your cache and a get a good capture of working and non working cases. Unlike a pure httpwatch or HAR capture, you will see if there is unexpected traffic that might be coming from a side-loaded application. (though if its https, you can't decrypt it) --John
