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)

Thank you for posting this! It was driving me batty. I know my EAS staging builds were installing on my dev devices just fine a few days ago, but mysteriously failing this morning? At least I have something to watch and check for in the future.

Just wasted an hour thinking it was on my end. <sigh>

Same issue here. We use expo application services ad-hoc builds

Yep same here - was so confused and went through similar steps to OP. But to no avail. Having to resort to using the simulator but not ideal!

would’ve been great to know before i went digging in derived dependencies, revoked half my certificates and devices, went digging through my phone’s dev mode configurations… 😅😅😅

For local development to unblock , one can try : Offline development profiles - this basically ignores the ppq checks.

Wow, I've been going insane the last 2+ hours trying to figure out this, glad I found this post and im not crazy. Seems like a deeper issue we need apple to solve.

Tried so many things. Frustrating, because I thought it was a local issue. After trying on different iPhones, different accounts, I started doubting it is an Apple issue. Then I found this topic.

Same here. Same failures on multiple devices.

Well one of us basically hosed his entire app fighting this issue until I found this. SO this 502 has done significant damage to my app and I wish there was a way for me to reset today rather than having to go chase the world. I deleted certificates, rebuilt them and I run a few apps. Damnit Crapple.
