Hello all, We have built our own MDM solution as we plan to support quite a few devices running iOS. Manual activation is running fine and devices are checking in. We have setup ABM with Device management service setup and linked to our MDM. We have added reseller via Apple customer number and purchased devices are showing in ABM. We have setup default management service assignment as well. When we are setting up a device it gives an error: Remote Management The configuration for your iPhone could not be downloaded from . cancelled Error in the device log is as follows: Jun 11 14:16:36 iPhone Setup(DMCUtilities)[626] : <DMCHTTPRequestor: 0x84cfd7d40> cannot accept the authentication method NSURLAuthenticationMethodClientCertificate Jun 11 14:16:36 iPhone Setup(CFNetwork)[626] : Task <663D2346-4B73-4DB2-A134-B1A7DC58E70B>.<1> auth completion disp=2 cred=0x0 Jun 11 14:16:36 iPhone Setup(CFNetwork)[626] : Task <663D2346-4B73-4DB2-A134-B1A7DC58E70B>.<1> summary for task failure {transaction_duration_ms=285, response_status=-1, connection=7, reused=1, reused_after_ms=0, request_start_ms=0, request_duration_ms=0, response_start_ms=0, response_duration_ms=0, request_bytes=0, request_throughput_kbps=0, response_bytes=0, response_throughput_kbps=0, cache_hit=false} Jun 11 14:16:36 iPhone Setup(CFNetwork)[626] : Connection 7: TLS Client Certificates encountered error 1:89 Jun 11 14:16:36 iPhone Setup(CFNetwork)[626] : Task <663D2346-4B73-4DB2-A134-B1A7DC58E70B>.<1> finished with error [-999] Error Domain=NSURLErrorDomain Code=-999 UserInfo={NSErrorFailingURLStringKey=, NSErrorFailingURLKey=, _NSURLErrorRelatedURLSessionTaskErrorKey=, _NSURLErrorFailingURLSessionTaskErrorKey=, NSLocalizedDescription=} Jun 11 14:16:36 iPhone Setup(CFNetwork)[626] : Connection 7: encountered error(1:89) Jun 11 14:16:36 iPhone Setup(CFNetwork)[626] : Connection 7: cleaning up Jun 11 14:16:36 iPhone Setup(CFNetwork)[626] : Connection 7: summary for unused connection {protocol="http/1.1", domain_lookup_duration_ms=0, connect_duration_ms=0, secure_connection_duration_ms=0, private_relay=false, idle_duration_ms=0} Jun 11 14:16:36 iPhone Setup(DMCUtilities)[626] : <DMCHTTPRequestor: 0x84cfd7d40> failed to communicate with the MDM server.

Hello, We have filtering logic that is being loaded into PacketTunnelProvider network extension for processing web traffic. The issue we are facing is the 50MB cap is being hit after browsing a few websites and the OS terminates the PacketTunnelProvider. What would be the best way to tackle this problem? A few ideas come to mind and would appreciate any support on them: using IPC (Inter Process Communication) to move the filtering logic back to the main app (if this is possible) we could move the filtering in Filter Control Provider however the limitation on there is that we cannot perform HTTP response modification which is imperative for the workings of the filtering. We have same solution working fine on Android and app is using about 270MB in worst case (however in Android there is no limit to network extension as the VPN provider runs inside the app) The project target market is in excess of 50,000 devices We would appreciate any support on the matter.

For iOS 15 was: Provider Limit (MiB) packet tunnel 50 app proxy 15 filter control 12 filter data 6 DNS proxy 15 app push 24 Is there official documentation on these limits?
