Please note the web.config file in ScadaWeb\plugins\Scheme also needs to be edited for HTTPS to work corectly. Else the schemes cannot be grabbed by the plugin. (The console -F12- shows “404 not found” errors)
Also, please note that after enabling HTTPS in IIS, https://localhost will not work (and should not) because the SSL certificate is for the public domain name and most probably doesn’t include the localhost domain.
So the current issue is related to IIS configuring, not Rapid SCADA. I suggest watching some videos in the internet how to setup HTTPS on IIS. Also we can configure IIS for a fee.
