Thanks for your replies, let me provide the context
We have a lot of hotspots (several hundres) running with Mikrotik routers for several years with many models from hex to CCR.
They are set with external captive portal (ADIPSYS Hotspot Manager) + signed SSL certificate with HTTPS and https-redirect set in profiles.
Without HTTPS / https-redrect on RoS v6, we had warnings during the POST process with modern browsers that detect when the portal in https is then switching to http post.
So we added an SSL certificate and all is working good.
We had recently a RB4011 with RoS 7.6 and noticed that https-redirect disappeared.
We did a simple test with the same setup than usual and a laptop running win11 connected
With our standard setup, when we do that, the browsers (edge, firefox) can identify that the laptop is behind a hotspot, and are pushing the user to click on a link with trigger the captive portal appereance. I can provide a screenshot of the message you get but this is a classic message.
With RoS v7.6, it did not happen : the browser could detect that the laptop was behind a hotspot
And if the user has the browser set with a https URL (which is very likely to happen), you get an error (just normal)
Tested with Firefox, Edge, Chrome.
I did not yet test on Android / iPhone, I hope it works but to be checked. But my first concern is that for hotspots on which we have users running a Windows laptop, which corresponds to a significant amount of users, removing the https-redirect will for sure increase the calls to technical support.
All Wi-Fi vendors are keeping the "HTTPS redirect" feature, so my suggestion would be to keep this feature even if you think this is not relevant. Because on the contrary to what you say, when you run WiFi Hotspots, you have a looooot of devices running multiple operating systems, old and "modern".
And Windows11, which is what I would call a modern operating system, did not achieve correctly this detection with RoS v7.6, while I guarantee it works very well with the https-redirect feature on RoS v6 firmware.
I can provide more info if you want to reproduce it.
