Trying to add flux plugin but keep getting prompted with error



I am trying to add the flux plugin for Grafana. However, every time I press save & test I am prompted with a window within chrome that asks me to login with a username and a password with the message: “Your connection to this site is not private”. I’m not to sure why I am getting this error, but feel as if it must be a configuration error? Has anyone else ran into this problem? Thanks in advance to all of those who reply. I have attached some pictures to this post. Capture

If it matters, I have the regular InfluxDB plugin running fine as my default with no issues.
