I tried to control my Ultimaker 3 with the app, but I have trouble connecting. When I open the Ultimaker 3 app the printer shows . When I click the printer I can see the camera stream. But when I click 'connect to this Ultimaker 3' it does say that the printer is not connected. Both devises are on the same Wifi network My phone is Samsung Galaxy S7 edge I have no problem with controlling the Ultimaker 3 via Cura on Windows How can I solve this?
