If you are talking about the steps where wolfgang adds a lets encrypt cert, bluehost is not a recognized DNS provider. If you are talking something else could you provide some additional detail please?

Edit: Just found this, will read more on it as I think it relates to your question. https://eamonnsullivan.co.uk/posts-output/ssl-setup/2024-04-01-setting-up-ssl-for-my-local-apps/

My internal network is blocked off from the internet and I’m not actually planning to enable tailscale for VPN in (my understanding of its purpose). This is really just so I can use sub domains like ‘homebox.mydomain.space’ to access and get a registered SSL certificate to switch all internal over. I’m not using the duckdns that Wolfgang did because I already registered a good custom domain that I use for my e-mail.
