Whitelist Freemius URL's & IP Addresses for Licensing
If your site can't verify your license key, it may be that your WP Security Plugin, Server, or Firewall is blocking Freemius' (our ecommerce/licensing partner) servers. If that's the case then your site won't be able to connect to their API to activate and verify your license key.
You'll need to whitelist (or add an exception) for the following addresses and IP's:
- api.freemius.com - IP address: 34.209.145.181 (port 8080)
- wp.freemius.com - IP address: 104.18.54.29 (port 8080)
