Roon Remote on Mac flashes intermittently after Nucleus installation (ref#QFOK80)

Hi! What’s not quite right with Roon?

· None of the above quite fits

· App interface looks or behaves oddly

· Two weeks ago, my Roon remote (Mac) would flash every few seconds, sometimes going back to the Roon loading logo. I was running an old ExaSound server, so I figured that it was left behind after many updates. Just installed a brand new Nucleus, went through three update cycles and the same thing is happening again.

I'm attaching a movie of the flash.

When using the remote on my iphone, it works fine.

Here's the Roon data from the configure page online:

· Nucleus hardwired via cat 5 to Netgear 8 port gigabit unmanaged hub to a tplink wifi router. Mac has trouble whether hardwired to the network or via wifi.

Update: the flashing goes away for a while, but when it comes back, it sometimes leads to the music stopping, or the server being lost (reconnect shows red dot). I’ll reboot the server and reboot the Mac (brand new macbook pro, latest software) and sometimes it seems to help, but not all the time…

Working with Claude, I checked a few things.

No: Little Snitch, Lulu, a corporate MDM profile.

No: Name conflict

I left the mac and the nucleus overnight (with Roon remote quit) and restarted today and so far, no flash. Superweird.

If the flash comes back, I’ll try:

Next time it starts flashing, open Terminal and run sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder. If the flashing stops within a few seconds, that’s your answer and we know where to look.

Will keep you posted. Ideas welcome.
