New DBs breaking Hosts

I created 3 new Databases: QA, LAB and PROD.
I updated hosts telegraf outputs.influxdb to: database = “LAB”

Any host not pointing to telegraf DB shows a red state in Chronograf and has topped receiving data.
Service on hosts restarts without errors.

If any host is changed from the default DB (telegraf) then they seems to break.

Any idea what is happening our how to get around this?
