Cerbo GX lost internet connection via Ethernet since Update to 3.55

Hi all,

since I upgraded to 3.55 I lost internet connection via the Ethernet interface. Went back to 3.54 without success. Although the Cerbo should fallback to wifi connection, it keeps disconnected from internet until I plug out the ethernet cable.

Reboot didnt’t work
Static IP didnt work
Setting a new default route via SSH worked, but isn’t persistant

Anyone else experiencing this (strange) behaviour?

Best regards,
Simon
