Web Browser Reports 330 Error Content Encoding

Problem Description

In rare circumstances you may come across the following error in your web browser when accessing one of the Nagios products:

Content Encoding Error

The page you are trying to view cannot be shown because it uses an invalid or unsupported form of compression.

* Please contact the website owners to inform them of this problem.

Error 330 (net::ERR_CONTENT_DECODING_FAILED): Unknown error.

 

 

Resolution

The Apache web server requires zlib.output_compression to be configured to On in the /etc/php.ini file.

Execute the following command to open the file in vi:

vi /etc/php.ini

When using the vi editor, to make changes press i on the keyboard first to enter insert mode. Press Esc to exit insert mode.

 

To locate the line zlib.output_compression = type the following:

/output_compression =

 

This should take you directly to the line. Change the setting to On:

zlib.output_compression = On

 

When you have finished, save the changes in vi by typing:

:wq

and press Enter.

 

The last step is to restart the Apache service using one of the commands below:

 

RHEL 7 + | CentOS 7 + | Oracle Linux 7 +

systemctl restart httpd.service

 

Debian | Ubuntu 16/18/20

systemctl restart apache2.service

 

 

After the service has restarted the problem should no longer occur.
