same thing here. here is what I have tried: Tested on iPhone on both Wi‑Fi and cellular: same failure. -Checked iPhone Settings → General → VPN & Device Management: no developer cert/profile shown to “trust”. Regenerated signing in EAS: Ran eas credentials -p ios (logged into Apple Developer team) Deleted/revoked the existing Apple Distribution certificate Let EAS generate a new Distribution certificate and new Ad Hoc provisioning profile including the iPhone UDID. Rebuilt multiple times after credential reset: Verified the iPhone UDID was included in the ad-hoc profile by re-selecting devices Ran eas device:create (Website flow) Rebuilt and chose “No, let me choose devices again”, selected the target iPhone. Checked Apple verification endpoint reachability from iPhone: https://ppq.apple.com intermittently returned 502 Bad Gateway, later returned ok. Checked EAS build list and ensured installing the latest build ID from March 10, 2026 (not older IPAs signed with the revoked cert). Noted possible interaction with VPN config on device (VPN config appears to disappear after reboot), suggesting network/proxy/filter could be involved.
