Description of Issue
Using iPad Mini 3 Roon remote APP connect to MAC mini Roon Core but stay in “Choose your Roon Core” this page like below and can’t connect anyway. But if I use MAC mini as Roon Remote software it can still played music correct so not sure what went wrong there.
Please help to figure out what is the problem here.
Cheers
Dave
Hey @Dave_Lu,
Please start by rebooting your router and network.
If you have any other active firewalls or antivirus applications on your core (such as McAfee, Bullguard, Little Snitch, ect.) it would be a good test to temporarily disable them and see if there is a change in behavior. If it does, then you know you will need to add an exception to the firewall for proper Roon communication.
Please make sure that I would take a look to make sure that both Roon.exe and RAATServer.exe have been added as exceptions to your firewall settings as well 
Please let me know if that helps!
Hi Ben:
I try several times of rebooting my router and my network but the problem is still there…
Any other possibility of MAC side’s setting or OS level issue?
Best Regards
Dave
Hi @Dave_Lu ,
Did you allow the Roon app to access your local network? You would need to configure this, if you haven’t yet:

Hi Roon Support team: My iPad got an automatic upgraded OS then looks problem solved… The Local Network is default on so not sure where the problem is but it is working now…
Cheers
