504 Gateway Time-out The server didn't respond in time. How to fix it?

Question

The client requested to download a compressed log file, using Ext.js a form submission on an embedded iframe. Request was sent to server, which has Apache and JBoss

Answer 1

Check your apache error logs. This can also be caused if the file size limit is set too low.

Answer 2

In my case more simply. I forgot to disable the Proxy extention in the browser.

Answer 3

The servlet was taking a long time to compress the log files, and Apache's timeout was set to 2min.

The error was fixed by increasing the TimeOut Directive on the httpd.conf file:

#
# Timeout: The number of seconds before receives and sends time out.
#
##Timeout 120
Timeout 600
