Web-hosting question: if I have html files on my RPi, which I can view locally on my home network, how can I publish those so they are available at a domain I have registered with Squarespace?

I don’t want to use the RPi as a web server, but would rather push those html files. I looked at Cloudflare, but I have to import from there manually rather than being able to push the files. (The html files are updated every five minutes so importing from CF isn’t feasible.) Also, I don’t want to use Squarespace for web-hosting. Thanks! #asknostr
