Prelego eQMS — 21 CFR Part 11 Electronic Signature
Troubleshooting
- "Authentication library failed to load" — The Microsoft login library is loaded from a Microsoft CDN. A corporate firewall or browser extension may be blocking it. Try a different network or browser, disabling extensions, or allowing
alcdn.msauth.net through your firewall.
- Stuck in a login loop or rejected after signing in — The service requires a fresh login completed within 5 minutes. Do not leave the page sitting open after it prompts you to sign in — complete the Microsoft login promptly and return immediately to click the sign button. If you are still rejected, close the tab and use the original link again to start fresh.
- "Missing required query parameters" — For document approvals, this page should be opened from the signing link in the PR status comment. For training records, use the link in the training issue. Do not bookmark or navigate to
sign.prelego.ai directly.
- Submission fails with a server error (blob write error, workflow trigger error, etc.) — These are infrastructure issues, not user errors. Wait a moment and try submitting again; re-submissions with the same details are safe. If the error persists, contact your eQMS admin.
- PR still shows as pending after signing — The verification workflow can take a minute or two to run after your signature is recorded. Refresh the PR page after a short wait. If it is still pending after a few minutes, you can safely re-submit the signature using the same link. If the problem persists, contact your eQMS admin.
