Advanced information and configuration
If you want to know more about the technical details of Wordfence, you will find the answers in this section.
Wordfence has its own “Automatic Update” function. If you enable this, new versions of Wordfence will automatically be installed on your site.
If your site is hosted on a LiteSpeed web server, please read the help page about configuring LiteSpeed to ensure that the automatic updates of your Wordfence plugin complete without any problems.
In very rare cases, allowing Wordfence to update automatically can be problematic because the update may fail and you won’t know about it until you login to your site and see that Wordfence is missing from the list of plugins for example. This can also happen to other plugins that have a feature to update automatically and not just Wordfence. Often site owners will try to install Wordfence again and be presented with a common error message containing, ‘Destination folder already exists’.
An automatic update of Wordfence is usually related to a problem on the hosting server. The update process involves removing old files, extracting the new plugin and then copying over the new files to the plugin location. On some hosting servers that process can exceed the PHP max_execution_time or even the gateway timeout. It is usually during the last part of the transfer when the new files are copied over that issues can occur.
To resolve this you can manually delete the Wordfence plugin directory in the plugins directory below:
All of your plugin settings will remain intact as they are stored in the database.
You can then reinstall the plugin again on the WordPress Plugins page.

Servers and IP Addresses
Wordfence infrastructure is hosted completely in the cloud. We are spread across multiple availability zones to reduce the likelihood of service outages.
Wordfence Central and plugin services use the IP addresses below to connect to sites that use the Wordfence plugin. These IP addresses are identified as outbound.wordfence.com. If you use Cloudflare with “bot protection” or other strict rules, or if you have other other types of blocking of inbound traffic aside from the Wordfence plugin, you may need to add these addresses to your allowlist:
If necessary, instructions for allowlisting on Cloudflare are available here.
Plugin services are hosted on the addresses below. In rare cases, if your server limits connections from your site to the internet, these are the IP addresses that you would need to add to your allowlist:
Note: Cloudflare users generally do not need to allow these IP addresses.
Wordfence servers previously used these addresses, which can be removed if you had allowlisted them in the past:
