Error Solver

How to fix: Portal authentication failed.

What happened?

The government portal (LCPtracker, AASHTOWare, etc.) rejected your login credentials or API token. This isn't a file format error — it's an access issue that prevents your submission from even being processed.

The Zero-Tolerance Solution

XMLExpress Enterprise Prime includes credential management — store and rotate portal credentials securely, with audit logging for every submission attempt.
