Since around September (iOS 26 release), i'm unable to test my app normally. It says "internet connection is required to verify [my certificate id]", or just crashing. All terms and conditions accepted, everything is valid, certificates are OK.

Reinstallation via xcode does not help. Removal of provisioning profile, generating new does not help. Revoking of certificate and generating new does for around week, then it happens again, but do i need to do it every week now?

In logs i see the following:

default  amfid  validation failed because of missing trust and/or authorization (0xe8008026)
error   amfid   not valid: 0xe8008026: The provisioning profile requires online authorization.
error   amfid  Unexpected MISError (0xe8008026): The provisioning profile requires online authorization.
default  +0300  amfid  /private/var/containers/Bundle/Application/5B8E560E-75B2-46EF-8606-02072D99E9CF//Frameworks/oss.dylib not valid: Error Domain=AppleMobileFileIntegrityError Code=-400 "An unknown error was encountered" UserInfo={NSURL=file:///private/var/containers/Bundle/Application/5B8E560E-75B2-46EF-8606-02072D99E9CF//Frameworks/oss.dylib, NSLocalizedDescription=An unknown error was encountered}
default   kernel  AMFI: code signature validation failed.

It looks like apple validation servers are not working, or is it iOS bug? All provisioning profiles are showing like "valid" in apple developer center.

My network is not behind a proxy, connection is direct.

If use EXACTLY the same app, signed with the same provisioning, same signature, on another test device, it works! When i reset current device to default settings and installing the EXACTLY same app after it, it works as well.

Looking for a help from apple developer support

Having this same problem. I've tried so many things.

  1. Rebooted iPhone (twice)
  2. Tried installing multiple different apps
  3. Cleaned build folder in Xcode (multiple times)
  4. Removed and re-added Apple ID in Xcode → Settings → Accounts
  5. Toggled automatic signing off and back on
  6. Deleted app from iPhone before rebuilding
  7. Attempted to clear local provisioning profiles (~/Library/MobileDevice/Provisioning Profiles/ — was already empty)
  8. Revoked development certificates from developer.apple.com
  9. Let Xcode regenerate fresh certificates and profiles
  10. Disabled iCloud Private Relay (was already off)
  11. Verified no VPN, content blockers, or DNS profiles active
  12. Tested on cellular only (WiFi disabled)
  13. Verified Date & Time set automatically
  14. Reset Network Settings on iPhone
  15. Reset All Settings on iPhone
  16. Toggled Developer Mode off and back on
  17. Disabled Do Not Disturb / Focus modes
  18. Checked Apple System Status page

Jweeces, I don’t think you’re hitting exactly the same problem as Tonnew. Rather, I think you were being hit by an infrastructure outage yesterday. Based on the posts at the end of this thread (10 pages, wow!) it seems to be resolved. Reply back here if you continue to have problems.

@Tonnew , Sorry I missed your thread the first time around (I suspect I was out of the office). I you continue to have problems with this, please post an update here and I’ll take a look.

Share and Enjoy
