A list of hosts that you need to whitelist in your firewall to allow Xamarin’s platform to work for your company.


In order for Xamarin products to install and work properly, certain endpoints must be accessible to download the required tools and updates for your software. If you or your company have strict firewall settings, you may experience issues with installation, licensing, components, and more. This document outlines some of the known endpoints that need to be whitelisted in your firewall in order for Xamarin to work. This list does not include the endpoints required for any third-party tools included in the download. If you are still experiencing trouble after going through this list, refer to the Apple or Android installation troubleshooting guides, or contact Xamarin support directly.
