Hi, i have this situation:
I used a mikrotik routerboard for easy captive portal and she redirect users to an external webserver that offer offline functions (like video, description etc...).
The problem is:
Windows, IOS, and Linux works fine with this method, if you connect to wifi a popup with the content of webserver appear without problem, Android no...
In Android you connect to wifi and after few seconds it say "No internet connection avaible" no popup/captive portal detected (In some phone facebook messenger detect captive portal but the android system not).
If i connect the routerboard to internet Android start to working!!! But my implementation of this system is designed for working only without internet.
Please you can tell me if there is a workaround for Android or a way to do this?
