I have been getting this message when I add music locations on folders that have say 100+ or more albums in it. I do not get the error when I link file paths that are smaller (less than 100 folders/albums) so i don’t think its any find of firewall issue. All the music files are on a secondary internal hard drive (not on the main ‘C’ drive). Seems like some kind of timeout issue
I am using the S2 app on a Windows 11 machine and have a variety of speakers connected (Era 100, Play1, Sonos One).
