An external site with phone browser give to me the URL : perspective://mydomain.com:443/myproject  
the phone ask me to open the project in the perspective app, i click yes and perspective app start loading the project but after 2 second of loading show me “no gateway connection, check your internet connection and try again”.

the app logs show “400 bad request . the plain HTTP request was sent to HTTPS port. microsoft azure application gateway”

In ios app everything run correcty . ONLY with android app give me this error with last ignition version
