Error on opening Micro Focus Enterprise Analyzer Workspace on Appstream

This error you're encountering is likely related to a database authentication issue for workspace path in Micro Focus Enterprise Analyzer on AppStream 2.0. When you try to reconnect to a previously created workspace, the system might not be able to authenticate correctly due to changes user permissions.

From the error message it seems the error is occurring while authenticating to the Database with username as per https://docs.aws.amazon.com/m2/latest/userguide/set-up-ea.html#tutorial-ea-step3 .

Database : D__PhotonUser_My_Files_Home_Folder_ws_wsCardDemo And username : EC2AMAZ-V375MAJ\PhotonUser

Please review the configuration provided during deployment. From the Amazon RDS instance running PostgreSQL including all the other prerequisites.

The username should have required permissions on the database, and has valid credentials updated. Since Photon User is a default user in Appstream, you may test using a domain user which is recognized across Apstream and RDS instances.
