Hi kelvin,
you could try to change the URL from "https" to "http". This could already solve your issue.
But I can really recommended this nice How-To to you: Getting started with IndluxDB on ctrlX CORE. This can probably help you to set this up correctly.
In addition you could also take a look at Telegraf, which you can use instead of Node Red to get Data from Data Layer to InfluxDB.
Best regards,
Nick
