Octodash menu is saying socket is dead

[steakfrosch322]

Hi,
While i'm just printing something I noticed that in the lower right corner of the printing menu of my octodash screen it says "socket is dead" (see photo) instead of operational, what there normally is written. And because it doesn't directly sound good, but everything is working like normally (Webinterface, the printing, etc.) I just wanted to ask what it could be. I'm using a raspberry pi 4 with the 7 inch touchscreen and an Ender-5. Thank you in advance.
