Can I access Notes Station only on HTTPS?

[Skeptical.me]

Hi,

I'm currently using a QNAP TS-251 QTS 4.2.2 Build 20161214

I'm still new to using a NAS, Web Servers, and Linux (Command Line) etc.

I share my Wifi and want to keep Notes Station secure within my network. I want to access notes station within my network only using a HTTPS connection. Am I able to access Note Station only on HTTPS? I can access it on https://192.168.1.256/qnote/ but its still accessible on the on the http url.

Just to let you know in Settings > System Administration I have enabled secure connection and forced secure connection HTTPS.

Any help is really appreciated. Thanks.
