I had been testing a firmware on a voron 0.2r1 which started out with a voronprinter.local type name
knomi2 was able to resolve this on the network and connect. when I changed the hostname to anything like
voron-02-pro.local ( which is a resault of putting the hostname to "voron-02-pro " knomi2 could no longer connect as if it wasn't able to resolve it.
did the typical reset knomi2 and setup from scratch, power cycling to reboot, nothing fixed it until giving it the actual IP
this means ideally if this isn't possible it should be documented, if it should have handled it, then hoepfully they'll find why
