Online-Medien sind nicht möglich

Hello everyone. Sorry for my bad German, but I use a translator. In a recent attempt to enable wireless Carplay on my brand new Tarraco, I made relevant adjustments to enable WiFi and wireless Carplay, but it didn't work and I also got an error (red bell on top right) and on the pull-down Get bar that means "Online media is not possible, please connect to WLAN". I restored the backup made with VCTOOL which changed all the customizations to their original state and restored the factory settings on the MIB, but I get the same error message on the screen every time the system starts. I can see online media disabled in 5F adjustments.
