A fully managed end-to-end service for digitally signing code, documents, and applications. (formerly Trusted Signing)
Submit Microsoft Authenticator diagnostics and open an Azure Support case before creating a third validation request, because the second attempt’s 504 networking_error and final Validation Fail status do not reveal whether Face Check or the Verified ID presentation failed.
What can be concluded
- First attempt: The displayed “Face Check failed” message identifies the failed step.
- Second attempt: The
504 networking_errorshows that a technical error occurred during presentation, but it does not establish the ultimate backend rejection reason. The generalValidation Failstatus cannot distinguish a network/presentation failure from a Face Check failure. - Similar Artifact Signing reports describe HTTP 504 errors during Verified ID presentation, including reports involving Japan, but they do not establish the cause of this specific transaction.^1^
Microsoft Support must correlate the timestamp, correlation ID, validation ID, and Authenticator diagnostics with service-side records. Repeated unexplained Artifact Signing failures have previously required backend investigation.^2^
Before another attempt
- Send Authenticator logs now
- Open Microsoft Authenticator.
- Select the top menu → Send feedback.
- Select Having trouble?
- Submit the form and logs.
- Record the resulting incident ID.^3^
- Create an Azure Support request
- In the Azure portal, open Help + support → Create a support request.
- Select the affected subscription and Artifact Signing resource.
- Ask for backend correlation of the failed Verified ID presentation.
- Both identity-validation IDs
- Correlation ID from the second attempt
- Exact UTC timestamp:
2026-11-11T12:11:12Z - Authenticator incident ID
- Artifact Signing region, account SKU, and validation type
- Phone model and operating-system version
- Microsoft Authenticator version
- Whether Wi-Fi, mobile data, VPN, or proxy was in use
- Screenshots of
Face Check failed,504 networking_error, and the failed portal status
- If support advises retrying, change the technical conditions
- Force-close every Authenticator instance, then reopen it.
- Update Authenticator to the latest Android or iOS version.
- Clear the browser cache or use another browser.
- Disable VPN or proxy services.
- Use a stable connection; switching between Wi-Fi and mobile data is a useful way to avoid repeating the same network path.
- If available, use another supported phone.
- Apply the Face Check guidance on any retry
- Use even, moderate lighting.
- Avoid direct sunlight, backlighting, and deep shadows.
- Clean and uncover the camera lens.
- Keep your face centered, fully visible, and facing the camera.
- Remove sunglasses or anything obscuring your face.^4^
Japan is supported for organizational Public Trust onboarding, so the country itself is not an unsupported configuration.^5^
The FAQ’s limit involving three attempts applies specifically when extra documents were required; it should not be assumed to apply to these Face Check and 504 failures.^4^
