Answer 1

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

Please notice that this solution might not be acceptable for the user. Instead of making a longer timeout, other option could be reviewing the workflow and implement the use case differently. E.g.: one request to start the operation (in this case compression), some notifications of the progress and a final notification with the link to download the file. – Ileum

Answer 2

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

Answer 3

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