Nginx Reverse Proxy with InfluxDB2

I would like to access it right now with the UI just to see if things are working.
But I do need to automatically send HTML end point requests from my IoT device so both I suppose ?

I have read up onthe HTML endpoints recently, I am still holding out hope that I can make this work as it really is my only option.

If subdomains is the only option you can think of then I will have to make that work if you would be so kind.
Right now I am using a free no-IP host name so I hope I can make a subdomain ontop of that one, I will try now.

If you could let me know the Nginx setup you suggest that would be great as even if no-ip does not let me do subdomains on their free service I will need to buy a actual domain of my own soon.
