Setup assistent is shown again after restoring db content on fresh installation

Hi everybody,

Description

I had to setup the whole machine from scratch and saved all mongodb content using ‘mongodump’ before.
Then reinstalled everything; Rocket.Chat shows the setup assistent. Stopped the Rocket.Chat service and replaced all mongodb content using the backup data using ‘mongorestore’. I can verify that the old db content has been stored (e.g. collection ‘users’ shows the previously existing users).
Restarted Rocket.Chat and expected the normal login screen but the setup assistent is shown instead.

How should I proceed? What data has to be restored as well?
Thank you!
Uli
