Umbrel not recognising Pi5 ethernet

Hi, I’m trying to install Umbrel OS onto an RPI 5. However it doesn’t seem to work with the network card. I’ve had a go trying to troubleshoot the error with nmcli, but it just doesn’t connect. It shows the ethernet connecting and disconnecting when I plug and unplug it, but it wont seem to connect to my dhcp. I also tried manually configuring an IPv4 address via one of the posts in this forum, but it still doesn’t like it. Anybody have any other things I can try? (tried the usual change the cable, use differrent port in the router etc)
thanks.
