1. Ensure the target URL for the data feed to match how the SSL certificate is configured.
2. Ensure the Instance name matches what is listed in the Archer Control Panel.
3. Ensure the credentials for account accessing API are correct (If using Anonymous make sure that the API application and WS folder in Microsoft IIS are set for Anonymous Authentication).
