What device(s) are you using Roon App on (pc, mac, phone, etc)?
Have you checked your firewall on the device(s) to make sure Roon.exe and RAATServer.exe are added as exceptions?
What do you see or what happens when you try to start Roon App.
Can you post a screenshot?
Thanks for reaching out. According to our diagnostic system it looks like you were able to log in, and your Roon Server appears to be active at the moment. Is the issue solved on your end or do you still need further assistance with this?
