Description of Issue -

What is the exact port forwarding error message you see in the Roon Settings → ARC tab?

So the only thing I see different from other cases is that only the “natpmp autoconfig” is not found. If I restart the app on my computer, ARC will function for up to a couple of days and then stop working again. Also seems to happen when I try scrubbing to a certain part of a track on ARC for iOS.
