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, not just a specific project.

Is anyone else experiencing this? Is there an ETA for the fix?

Environment:

Xcode 26.3 (17C519)
macOS 26.3.1 (25D2128)
iPhone 16 Pro Max, iOS 26.4 (23E5223k)

Adding my voice to this particular choir. Spent over 8 hours chasing this goose. We have a deadline for tomorrow (realistically tonight) to get our app up and running again.

The same issue. Developer Mode is on but not working iOS 26.3.1.

Wow what a waste of time! Like many here I spent the last few hours burning my setup down trying to find the cause of this issue... at least 2 hours into the outage we get a heads up here... https://developer.apple.com/system-status/

It appears the status page is not dynamic and requires manual updating. It also appears this is not actually a job function for anybody. I've actually never seen the status page update unless something has been down for 4+ hours. I am hopeful Apple will make this a priority.

Same here on Vision Pro. Reinstalled everything on a clean headset with same results: “This app can't run and must be verified.” Lost 4 hours!!
