Description of Issue

The Cambridge Audio EVO 75 stopped appearing in Roon today.
I changed nothing, I did nothing. I have now reset everything and it still doesn’t work.

The usual recommendation is to Reboot your Roon Core and restart the Roon endpoints when everything is back up and running


You haven’t told us what your Roon Core is running on. If it is on Windows, then Windows Update has been known to mess with Roon’s firewall rules.

If turning off the Windows Firewall temporarily as a test makes the EVO 75 appear again, then look to redoing the Firewall rules…

Hi @Craig_Blair,

It looks like you’ve been given some ideas. Is the issue still ongoing?
