On occasion, when you enter your license key under the Events > Settings > Licenses<\/strong> tab for one of our plugins, you might get a notification that says:<\/p>\n\n\n\n

“Sorry, key validation server is not available.”<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

This usually happens when something is blocking the communication between your site and our license key validation server. In most cases, this could be caused by a security plugin, a firewall, or a security measure set up by your hosting provider.<\/p>\n\n\n\n

If you have a security plugin installed, start by temporarily deactivating it for a short time while you re-check the validation. If the validation succeeds, then you might need to fine-tune the settings of the security plugin to allow communication with our server.<\/p>\n\n\n\n

In case you are behind a firewall, try adding the following IP address to the firewall whitelist and see if that helps with the validation. This might be set up by your host, so you can reach out to them for assistance.<\/p>\n\n\n

\nLicense Key Validation Server: 192.190.220.23\n<\/pre><\/div>\n\n\n
If that doesn’t work, you can try adding *.theeventscalendar.com<\/code> to the WP_ACCESSIBLE_HOSTS constant, along with WP_HTTP_BLOCK_EXTERNAL (true).<\/p>\n\n\n\n
To do that add the following code to your wp-config.php file. <\/p>\n\n\n\n
define( 'WP_ACCESSIBLE_HOSTS', '*.theeventscalendar.com' );\ndefine( 'WP_HTTP_BLOCK_EXTERNAL', true );<\/code><\/pre>\n\n\n\n
