Cannot get my Shellys to change to unicast for DNS

  • I rebuilt my network and moved my shelly 2.5s to a separate VLAN from my Home Assistant. I went to the Web ui for my Shellys and changed the ColoT to the address of my home assistant, made sure device discovery was turned on,
    rebooted my Shelly's, created a firewall to all the Shellys to reach my Home Assistant. My shelly's continue to send out multicast DNS requests. How can I change this?
