I’ve had MP3Tag for the Mac for years. Increasingly, it was not working when I tried to access my music library stored on my NAS. I deleted and attempted to download the app, but I do not have the license key. How can I get a copy?

Thanks,
David

Thank you. I was able to download it directly from the Apple App Store.
However, accessing my NAS-based library is still hard to reach. When I attempt to open an album stored on my NAS, my Mac shows the spinning ball. After a few minutes, I get this:
I’m not certain where the IP address is coming from, but that is not the IP address where my music library is located. How can I map MP3Tag to the correct address?
Thanks!

> I'm on MacOS 15.3.1 and MP3Tag 1.9.1 (115).
