- Network connections to the hosts below are initiated by the device, not by hosts operated by Apple.
- Apple services will fail any connection that uses HTTPS Interception (SSL Inspection). If the HTTPS traffic traverses a web proxy, disable HTTPS Interception for the hosts listed in this article.
Make sure your Apple devices can access the hosts listed below.
Apple Push Notifications
Learn how to troubleshoot connecting to the Apple Push Notification service (APNs). For devices that send all traffic through an HTTP proxy, you can configure the proxy either manually on the device or with a configuration profile.
