All of the above is not needed (but should be harmless) if you use
--provision* .

For dwh and reports, please pass also: --provision-dwh-db --provision-reports-db

Did you change the password in the db too?

Basically, that's the command you should run to debug. Once you make it
work, pass the password you use as --db-password.
Of course, --provision-* is easier.
