we have installed a new DMA at a tech partner lab which fails to start correctly.

Here some indications from the log files: any advice how to fix this would be much appreciated.

Hi Thomas,

If your SLDataMiner log file is stuck at 'Initializing Cloud Bridge..', you might need to uninstall and reinstall NATS; have you tried that as per Investigating NATS Issues | DataMiner Docs ? Let me know.

I reinstalled NATS but still does not start

Update : The DMA was unable to connect to its DB as the root user did not exist; after creating the root user, the DMA is back up.
