@Jotne: I will gladly explain our problem. This is a problem that's been causing us some concern and it shouldn't be rocket science, but we could not solve it so far. Here is the explanation:
We have a hotspot system using almost exclusively RB951Ui-2HnD routers. We have a login page hosted on our (radius) server behind a https:// address to give our users added security. With a v6.42.6 and some other v6.42.x when a user selects the hotspot WiFi network, the Captive Assistant in iOS and Android do their usual checks (with "Success") and after realizing that it's a hotspot network, they reroute the users to our
https://hotspot.mydomain.com URL. There, the login page is displayed and the user is able to complete the login process.
With later versions this is not working! The same thing happens, user selects our hotspot SSID, the Captive Assistant kicks in, the user is redirected to
https://hotspot.mydomain.com URL but the page is blank (light gray and no content of the page is displayed). Also there is no security warning or similar. There is just an empty light gray page in the limited browser of the CNA. This makes troubleshooting difficult. Same thing happens in a regular Web browser on the phone. When I enter manually in the browser the
http://hotspot.mydomain.com, the http:// page is displayed.
Obviously it's to do with https but we don't understand why the browser does not open the https:// page anymore with newer versions than 6.42.6 but http:// works. We really want and need to have our login page behind a https:// and i think this is standard today so I cannot believe that Mikrotik suddenly doesn't support this. Please help if you have had experience with this before. We are really stuck! I can provide any traces/screenshots etc that you might need to give you further clues. THANK YOU!
