Known issues with iOS affecting Edge Client 2.0.8

The following are known iOS issues that affect the user experience when Edge Client is used on an iOS device. These issues may be addressed in the future by Apple.

ID number Description
476958 If a fully qualified host is specified in the proxy bypass list, users navigating to the host using the short form make use of the proxy in iOS 7, but this bypasses the proxy on iOS 8. iOS 8 takes into account the DNS suffix for proxy bypass.
518576 After users trigger VPN On Demand, Safari displays the following error message, Safari could not open the page because the server stopped responding. Users fail to reach the internal resource until they refresh the web page. This only occurs when users try to reach a domain that ends in ".local."
557905 On iOS 9, if an managed app is being updated while Per-App VPN is active, the updated app might not make use of the active session until the active session is expired and a new one is created. As a workaround, wait until the current session expires, and restart the updated app.
559388 After users upgrade Edge Client to a later version (such as 2.0.7) on iOS 9, the following message might be displayed when launching applications that trigger VPN On Demand (including per-app VPN): Please launch Edge Client to enable the VPN connection. To address this issue, users, when prompted, should manually launch Edge Client to accept the use of VPN. VPN On Demand connections are not available unless users accept the use of VPN in Edge Client.
582315 If users first establish a VPN connection using VPN on-demand, the connection fails when the proxy is required to access the backend server. This happens when users enable proxy configuration in the network access resource, located on the server side, and the VPN configuration has VPN on-demand suffixes on the client side. To work around this issue, reestablish the connection by refreshing the webpage in Safari.
588205 When the iOS device goes into sleep mode, the on-demand connection terminates before the disconnect timeout. This can cause the iOS system to go into a non-recoverable state, disconnecting the VPN. In this state, Edge Client cannot reconnect, even when within the disconnect timeout limit.
591017 On iOS 9 with "Connect on Demand" enabled for a VPN configuration, the system downloads the proxy auto-config (PAC) file only after a delay. Users should wait for more than one minute after establishing the VPN tunnel so the PAC script downloads and applies.
591501 On iOS 9, when per-app VPN is triggered by Safari, the session is deleted after an inactivity timeout, instead of after the expected on-demand disconnect. Per-app VPN connections triggered by a provisioned application have sessions deleted correctly after an on-demand disconnect timeout.
596581 On iOS 9, if users create a VPN configuration that uses a client certificate, then deletes the Edge Client app, the certificate is removed as well.

Fixes in 2.0.8

ID number Description
547430 Previously, when an Edge Client configuration provisioned for client certificate authentication on iOS 9 was deleted, the client certificate was also deleted from the system store. This has been fixed.
562104 Previously, when Edge Client connected or reconnected to a VPN connection, the iOS VPN framework failed to download the Proxy AutoConfiguration (PAC) file and failed to apply the settings specified in the Network Access resource. Because of this, users were unable to access websites that required proxy settings in place. This issue is resolved.
578975 Previously, when users opened the Edge Client app on an iPad Pro, the client loaded but did not display the connection screen or the menu bar at the bottom. Users only saw the background. This could occur when users launched a new instance of the app rather than an application running in the background. This issue is resolved. The app user interface now displays correctly when users either launch the app or bring it up from the background.
