Flux plugin in grafana

I am using Flux Plugin in Grafana, when querying the data , I a getting network forbidden error( 403)

I have updated http_enabled = true in influx.config file

Sounds like an error while authenticating. Have you made sure your username and password are correct?

Yep, I have double checked my username and password credentials.

Dear Madhur,

did you configure a Default Bucket like outlined below?

With kind regards,

Since, I am using InfluxDb_1.7 version, do I need to configure this?
Even after configuring this, i am getting the same issue
