Chromecast with Fabric Wifi not working

Hello,

I have a fabric network both on wired and wireless configured by DNA Center but because of internal DNAC problems I modify WLC manually. Both Wifi and Wired are in the same network. When my Laptop and Chromecast both are connected with cable and in the same network, Chrome could find TV. However when I put my laptop in Wifi  Chromecast in cable it does not work. I checked with Wireshark no response for my SSDP discovery packet. I really need this to be configured as in second scenario as workers in my company in need for chromecasts.

The AP that I connect my laptop sits in different Edge switch than wired chromecast. 

Any help is appreciated.

I assume the problem is not with Multicast but with TTL=1 in chromecast discovery packet. I assume in fabric traffic between different switches are routed not switches so TTL=1 does no work.

That's the way the protocol is designed - it's only intended to be used on local subnet.
That WHY you need to use proxy/gateway if they're on different subnets.

Again, both laptop and chromecast sit in the same subnet. Only seperated by Fabric switches which use VxLAN for transporting traffic between. I think that can be a problem of VxLAN
