After the reset, the WiFi connection was lost.
So I wanted to reconnect the 4Stream app to the device. Despite resetting the 4Stream app (cache & data deleted), setting up the WiFi connection failed. It looks like there is a problem with the WiFi password.
I have entered the WiFi password manually and by copy & paste in the 4Stream app. Each time the router log says âWiFi device login failed (2.4 GHz): invalid WiFi key. MAC-Adresse: 00:22:6C:66:6C:32â
This is very mysterious because the device has already been connected to this WiFi
