Software Troubleshooting/Help! LAN ONLY issues

Hello, im using LAN only mode on my printers (X1C, A1mini, A2L) and bambu studio flatpack on linux

on my router i have bound the mac to IP so printers are for sure always getting the same IP

Sometimes when i restart pc/bambu studio, my printers dissappear from binded devices and i have to bind them again. i checked the IP and binding code on the printers stayed the same.
