Your documentation contains a direct link to the GeoLite2 download; Shortly this will no longer work.

Due to upcoming data privacy regulations, MaxMind are making significant changes to how users access free MaxMind GeoLite2 databases starting December 30, 2019. The databases will continue to be available without charge and for redistribution. However, you will be required to create an account and use a license key to download the databases, and agree to a new EULA that addresses applicable data privacy regulations.
