I thought it was worth mentioning that on a new install of Openwrt 24.10 in LUCI menu:
/cgi-bin/luci/admin/system/admin
the setting "redirect to https" does not redirect to an https address, nor does adding the https precursor in the server address redirect to the server; it is unreachable except in http only.
A work around for this was to install the package "px5g-standalone" or to pre-build with the added package to restore the feature.
The default package selection doesn't include SSL for Luci as far as I'm aware. I usually add the luci-ssl package which includes components required for SSL including px5g
