HCP Trial Hana MDC - wrong credentials

Hello all,

I am working on a small HCP project, where the data is stored in a Hana MDC DB.

I have successfully created the database, setup the roles, and could connect to it over REST APIs (xsodata).

After a couple of days, when trying to connect to the DB over HCP "SAP HANA Web-based Development Workbench", I keep on getting "Login failed : wrong credentials." When trying to connect to the "Catalog", I get a frozen screen with a "loading" bar, not loading anything at all...

Any ideas around that?

Thanks,

Sven
