F5 Access 2018 app shows "Unable to retrieve network access configuration" on iPhone 7 with iOS 12 (beta)
F5 Access 2018 app shows "Unable to retrieve network access configuration" on iPhone 7 with iOS 12 (beta) when we use Web Logon for authentication (for OTP codes). If we choose Native authentication (and remove the requirement for OTP), the VPN establishes just fine. On the server side, "Session deleted due to user logout request." when the user receives the error message. We're using split-tunnel VPN. A user reported getting the above error after upgrading to iOS 12 Beta and installing the F5 Access 2018 app. I have replicated this on a brand new iPhone 7 after upgrading it to iOS 12. Am suspecting this is an iOS 12 Beta bug, but it is a problem nonetheless. See below for the relevant part of the client logs. I also saw this old thread which refers to the exact same "Error 111" message on iOS as seen in the F5 Access client log: https://stackoverflow.com/questions/20454853/nsxmlparsererrordomain-111 Excerpt from client log: PacketTunnelProvider.swift, 477, startTunnel(options:completionHandler:), Session has been established VpnFavoriteListOperation.swift, 110, main(), VPN Favorites failed: Error Domain=NSXMLParserErrorDomain Code=111 "(null)" PacketTunnelProvider.swift, 484, startTunnel(options:completionHandler:), Network parameters have been received PacketTunnelProvider.swift, 487, startTunnel(options:completionHandler:), Failed to get NA settings Internal Error: VPN resource was not found PacketTunnelProvider.swift, 334, displayMessage(_:completionHandler:), Unable to retrieve network access configuration Full log: 2018-07-09,13:23:07:672, 264,7683,PacketTunnel, 48, PacketTunnelProvider.swift, 368, startTunnel(options:completionHandler:), ------------------------------------------------------------ 2018-07-09,13:23:07:684, 264,7683,PacketTunnel, 48, PacketTunnelProvider.swift, 369, startTunnel(options:completionHandler:), Release Version: 3.0.0 2018-07-09,13:23:07:698, 264,7683,PacketTunnel, 48, PacketTunnelProvider.swift, 370, startTunnel(options:completionHandler:), Bundle Version: 3.0.0.224 2018-07-09,13:23:07:704, 264,7683,PacketTunnel, 48, PacketTunnelProvider.swift, 371, startTunnel(options:completionHandler:), Build Date: Fri Mar 2 13:20:26 PST 2018 2018-07-09,13:23:07:709, 264,7683,PacketTunnel, 48, PacketTunnelProvider.swift, 372, startTunnel(options:completionHandler:), Build Type: CM 2018-07-09,13:23:07:712, 264,7683,PacketTunnel, 48, PacketTunnelProvider.swift, 373, startTunnel(options:completionHandler:), Changelist: 2509912 2018-07-09,13:23:07:715, 264,7683,PacketTunnel, 48, PacketTunnelProvider.swift, 374, startTunnel(options:completionHandler:), Locale: engelsk (Norge) 2018-07-09,13:23:07:718, 264,7683,PacketTunnel, 48, PacketTunnelProvider.swift, 375, startTunnel(options:completionHandler:), ------------------------------------------------------------ 2018-07-09,13:23:07:727, 264,7683,PacketTunnel, 48, PacketTunnelProvider.swift, 382, startTunnel(options:completionHandler:), Connection Parameters: Optional("serverAddress: https://fjerntilgang.tine.no,password: ,ignorePassword: false,passwordExpirationTimeStamp: -1,passwordReference: not-set,passwordExpired: falseidentityReference: not-set,postLaunchUrl: ,webLogon: true,launchedByUriScheme: false,vpnScope: device,startType: manual,deviceIdentity: assignedId: ,instanceId: ,udid: ,macAddress: ,serialNumber: ") 2018-07-09,13:23:42:181, 264,7947,PacketTunnel, 48, PacketTunnelProvider.swift, 166, checkForConfigurationUpdate, Request update configuration with "{ "savePasswordEnabled" : false, "weblogonAutoPopulateEnabled" : true, "clearPassword" : false, "enforceWebLogon" : false, "enforceLogonMode" : false, "launchedByUriScheme" : false, "timeStamp" : -1, "logonSucceed" : true }" 2018-07-09,13:23:42:222, 264,7947,PacketTunnel, 48, PacketTunnelProvider.swift, 477, startTunnel(options:completionHandler:), Session has been established (Session ID: c47c4cf6) 2018-07-09,13:23:42:446, 264,12807,PacketTunnel, 1, VpnFavoriteListOperation.swift, 110, main(), VPN Favorites failed: Error Domain=NSXMLParserErrorDomain Code=111 "(null)" 2018-07-09,13:23:42:454, 264,12807,PacketTunnel, 48, PacketTunnelProvider.swift, 484, startTunnel(options:completionHandler:), Network parameters have been received 2018-07-09,13:23:42:459, 264,12807,PacketTunnel, 1, PacketTunnelProvider.swift, 487, startTunnel(options:completionHandler:), Failed to get NA settings Internal Error: VPN resource was not found 2018-07-09,13:23:42:487, 264,12807,PacketTunnel, 1, PacketTunnelProvider.swift, 334, displayMessage(_:completionHandler:), Unable to retrieve network access configuration
