Pretty sure there’s not a per-domain setting for that. If you have HTTPS-Only Mode turned on in the settings it will always try to use HTTPS first and present a warning before switching to HTTP.

If you want to continue using HTTPS you can setup your own CA certificate to sign certificates for your .LAN domain names. All you need to do then is add the CA certificate to your trusted certificates in Firefox and the signed certificate to the device hosting the HTTPS service.

EDIT: TIL there an exclusion feature. Neat. I didn’t see this on Firefox for Android though. https://support.mozilla.org/en-US/kb/https-only-prefs

You mentioned ping. If you’re using Termux you may need to manually update its DNS settings (different from the system DNS). The file is /data/data/com.termux/files/usr/etc/resolv.conf

To make it roam you probably want your home dns first then some internet resolvers after that.

In the US they are usually governed as real estate legally. You can resell it, but most people aren’t interested in paying the maintenance fees. You’ll find all sorts of timeshares out there being resold for 1$ because they just don’t want to pay the maintenance fee anymore.

The -k argument on my openssl accepts a passphrase, not a file. You likely encrypted with the filename as the secret, not it’s contents. Perhaps you should use -kfile instead.
