Troubleshoot Dynamic Analysis prescan errors

Prescan errors comprise two types: connection errors and authentication errors.

These tables provide corrective actions for prescan connection and authentication errors. After troubleshooting the problem you are experiencing, verify the Dynamic Analysis configuration and run prescan again. If a failure persists, contact Veracode Technical Support.
