How to activate the license key from behind a firewall / without internet access

When you purchase a Premium edition of an of our plugins you need to activate the license key. During activation, the plugin communicates with the below URLs to confirm the validity of the license key:

• https://wp.freemius.com
• https://api.freemius.com

If your WordPress website and plugin are installed behind a network firewall with no internet access, white-list the above mentioned URLs to activate the license key. For optimum security you can also restrict access to these URLs to just the web server on which the plugin is running.

No firewall / internet connection exception?

Unfortuantely at the moment it is not possible to install the plugin on a website that is completely isolated from an internet connection.
