TP Link s7 Routers (x5) Mesh WiFi
Roon device is directly connected via a 5 port GigE switch that connects it to one of my routers and to the music library stored on a Synology NAS - Nothing WiFi for the NAS and ROON box.

Description of Issue
All 3 of my my Google endpoints disappear from Roon on a daily basis. A restart of Roon brings them back. This has happened more since the last upgrade but it is now daily. Both are using Chromecast Streaming. I work in IT and have done for 25 years so I’ve already gone through the networking, config side of things.
If it were a networking issue all of my endpoints would be affected.I have around 60 devices on my network, all of which work flawlessly. Only Roon experiences the loss of the endpoints and once it sees them, it is able to stream to them without fault. The issue is Roon losing them over a period of time when not in use. As I mentioned, I work in IT and for many years was a network engineer
Chromecasts and Roon rely on your router properly supporting multicast. Check your router for settings that might block multicast or mDNS. I have several Chromecast zones and don’t have any issues at all so it’s likely to be a local network issue even it’s not something you want to hear.

Carl, check the Roon log files for when (and possibly why) the Chromecast devices disconnect.
Q6. What can I do if the Deco units become unstable once they’re connected via a switch?
1.Try a different port on the Deco/Switch. On the main Deco, one port should connect to the modem/router to get internet, another port can be used for Ethernet backhaul. You can swap the Internet port and the Ethernet backhaul port for a try.
2.Try a different Ethernet cable.
3.Please try connecting two Deco units directly by using one Ethernet cable, bypassing the switch. If the Deco units become stable. It’s probably that you’re using a switch that does not forward specific multicast packets.
The Deco Ethernet backhaul feature is based on the standard IEEE 1905.1 protocol. However, we find that some switches, mainly the D-Link switches, will not forward packets based on IEEE 1905.1 protocol, causing all Deco units in a network loop and becoming quite unstable, you might consider changing another switch or contacting switch’s support directly. TP-Link Switches are mostly compatible with our Deco’s Ethernet backhaul.
Thanks for this. Multicast is enabled by default but I’ve just been reading about another Deco user that has had issues simar to mine. I’ll do some more digging
It’s great seeing you on the community and thanks for the update! Could you please reproduce the issue and share the specific date and time when the issue occurs?
Once you let me know this info, I’ll go ahead and enable diagnostics for your account so I can review the logging for clues.
If you’d rather do it yourself manually, please use the directions found here and send over a set of logs to our File Uploader.
I have the same issue since 2 weeks. Before I had no problems, I could always stream to my Google Nest. Now Roon sees the Nest just after re-starting (rebooting my NUC Roon server with Windows 11), but after appr. a day it is no longer seen.
Other apps (Google home, Spotify) still see Google nest and I can stream audio to it from Spotify, but no longer from Roon
