Connection failure after update

After updating Roon to version 1.8 my RoPieeeXL is not working.
I turned on my RoPieeXL and it was updating. After the update it wouldn’t connect with WiFi. So I took it apart and connected it with a cable straight into the router to configure the settings again.
Now the RoPieeeXL is working again but on the display I get the Connection Failure screen while the music is being played.
Any suggestions are appreciated.

try restarting your Roon core?
