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)

Same here. Wasted half an hour restarting, refreshing, reinstalling etc.

ran “curl -I https://ppq.apple.com%E2%80%9D in terminal and got the 502 message.

Does Apple know that this is happening and how severe it is since it is a work stopper? Also how will we know when the ppq server is back up?

Happening for us as well. We were testing a new build of one of our apps all morning and just started getting the Unable to Verify App message about an hour and a half ago. How do we know Apple is aware of the problem when the status page shows all green?

Like some I expect I spent ages dealing with the direct message before realising the ppl.apple.com was returning a 502.

Same issue. I constantly get this "Unable to verify app" error, this started happening around an hour ago.

Also tried rebooting my Apple devices, revoking the certificate and creating a new one, cleaning the build cache, trying a different app etc.
