Since the demise of freenom, I can no longer access my site using the cloudflare tunnel add on using domain.ga. I have a domain I use for other activities and I was investigating if I could use a subdomain on it to access my HA. I came across this guide that uses the cloudflare integration (I confess to not having been aware of it). I’ve come close to getting it to work. I can access using http://subdomain.domain.co.uk:8123 but I can’t get it to work using https. Any ideas how I might get it to work? Is it even possible?
So it depends whether you just want to point DNS record to your public IP and do port forward (use nginx as reverse proxy, but then you have to issue certificates and load them onto HA).
Or you can move your domain to cloudflare, use cloudflared addon - enable zero trust dashboard on Cloudflare website, create a tunnel on website, route public DNS record via tunnel to point to your local instance http://x.y.z.q:8123 and that is it. I have been using cloudflared ever since I learned about its existence.
If you configure tunnel via web, all you need to supply to addon is tunnel token - that’s it.
