Sorry I probably wasn’t clear enough; I know how it works and I’m not looking for remote access to my LMS through HA; my HA is currently set up for HTTPS so browsers won’t display LMS because it’s HTTP, even internally.
I have three options:
Secure LMS via Nginx (I don’t want to do this as for Let’s Encrypt I would need to expose LMS to the internet, which I don’t think is a particularly good idea).
Make HA HTTP and use Nginx for SSL (preferred option, though my HA will look a bit less elegant when it shows iFrame errors whilst away from home).
Wildcard cert and secure both sites with the same one (still exposes LMS to the internet but saves me having to remove HTTPS and use Nginx for my HA install; app for example will just use one URL).
Assuming the second option is best for me I’m just struggling with how to go back to HTTP; is it as simple as removing the HTTP lines from my configuration.yaml, adding these lines, installing the Nginx addon and pointing it to the cert files that the Let’s Encrypt addon dumps?
I just don’t want to do anything stupid like lock myself out.
