Datasource named nagflux was not found

I am running grafana-6.6.0 on CentOS Linux release 7.7.1908 (Core) using influxdb as timeseries database 1.7.9. I have added it in datasource and tested it. It works. I have queried the influxdb i am able to see the data but when i query it from Grafana UI dashboard, i am seeing Datasource named nagflux was not found
