Since this evening (March 10, 2026), I'm unable to launch any developer-signed app on my physical device (iPhone 16 Pro Max, iOS 26.4 beta 23E5223k). The error is: Unable to launch [app] because it has an invalid code signature, inadequate entitlements or its profile has not been explicitly trusted by the user. On the device itself, it shows: Unable to Verify App - An internet connection is required to verify the trust of the developer. What I've tried: Created a new Apple Development certificate Deleted and reinstalled the app Restarted the device Tested on both Wi-Fi and cellular Confirmed Developer Mode is enabled Removed all third-party CA certificates from the device Verified the code signature is valid (codesign -dv shows correct Authority chain) The root cause: https://ppq.apple.com is currently returning 502 Bad Gateway. I confirmed this both from my Mac (curl -s -o /dev/null -w %{http_code} https://ppq.apple.com → 502) and from Safari on the device. This affects all developer-signed apps, no
