Can't login to FTD GUI

[ChrisNye]

I am unable to login to the FDM GUI ISA3000 FTD 7.0.1 using the local admin credentials after initial setup on the CLI. I can access the the FDM landing page through the web browser but get a red x above the login prompt after entering the admin credentials. I have verified the new admin password is correct by logging out of the CLI and logging back in multiple times. I have rebooted the system and tried using Chrome and Microsoft Edge. I've followed the steps in the ISA3000 getting started guide configuration for the initial CLI configurations before attempting to login through FDM. Does anyone know how to resolve this issue?

I ended up re-imaging the device to a later version to resolve the issue.
