I've figured out the root cause: the Chromecast TV adapter was connected over a power line adapter (Extollo), which created connection problems. Not sure what exactly inside the power line adapter caused the connection problems, but after I connected with an Ethernet wire to the MX67, it worked again. To be clear the power line adapter worked fine for streaming, but somehow interfered with the Chromecast protocol preventing it from showing up in my streaming Apps on my smartphone. Thanks for all the responses.

Thanks for the replies so far. I've disabled the Bonjour forwarding, but that didn't make a difference, Chromecast works over wireless, and doesn't over a wired connection. I've noticed some oddities: Chromecast over wireless shows "Source IP and/or VLAN mismatch" issues in the event log (security appliance), and shows: source_client_ip: 192.168.128.12, source_client_mac: [xx], source_client_assigned_vlan: 1 Whereas, Chromecast over wired shows it either on VLAN 0 or untagged Other devices seem to be on VLAN 1 I didn't change any of the VLAN settings, but perhaps this gives a little more color on what's going on. P.S. on the multi-cast to uni-cast conversion, I've left that disabled, it really impacted the Google Home and Audio streaming: out of sync audio, and unable to set volume levels across devices in the Google Home app.

I'm using a MX67 that connects to a TV, if I connect through the MR33 casting works, if I use the wired connection I can see the Chromecast symbol in my streaming apps, e.g. YouTube, HBO, etc. but it says No Device Available. Ethernet and wireless connection (from the same Chromecast device) are on the same LAN/VLAN, it's a flat network, so is my smartphone. What I've done so far: Despite it being a flat network, I've enabled Bonjour forwarding and enabled a Layer 3 firewall rule that allows wireless clients accessing the LAN. I've also disabled the default multi-cast to uni-cast conversion which fixed issues with my Google Home but unfortunately didn't resolve my screen casting issues. When I had the MR33 connected to a non-Cisco router everything worked fine, but since I replaced it with the MX67 this is the one thing that keeps bugging me. I hope someone can help.
