On laptop I tried to add a local folder on C drive to Sonos. The Sonos controller on the same laptop gave the 1002 error code. This is a timeout?
Tried to find solution on web. Firewall had no issues and anti virus software wasn’t doing anything strange. Just in case, I turned off file scanning. Still have issue. Turned off the Windows firewall; still have problem.
Long story short, Kapersky has a firewall running, doh! Turned that off, Sonos can read local folder. Makes no sense. Why would a firewall block a local app from local folder? Probably because the local Sonos controller has to update the local network with that folder so that other controllers in house can also use it.
