Problems using Influx from the CLI

Hello everyone.
I am trying to work with Influx database from CLI and whatever command I type I always get the same error. It is shown in the following screenshot.

Screenshot_2.jpgError: Attempted to unmarshal error as JSON but failed: “invalid character ‘C’ looking for beginning of value”: Client sent an HTTP request to an HTTPS server.

Screenshot_2.jpgWhy can it be due? Could it be that it has something to do with security issues / certificates in the EPC?

What I’m trying to do is create a read-only user for the DashBoards I’ve created with Cronograf. Is there any guide that I can follow on this?

Many thanks in advance for the support.

Regards.
