can't connect after router restart.

Hi I have 3 printers 2 of them running klipper and 1 running ratos. Yesterday I had to reboot my router. After that the 2 klipper printers connected with no issues but I can't connect to my rig. Ethernet cable didn't help. It doesnt appear when I try arp -a either.

How can I troubleshoot this if I can't connect to the Rpi? Thanks
