I've been having the same issue on multiple machines. They each have their own ID but for some reason, 2 folders continuously get the "disconnected by owner" issue.
All the computers are using resilio sync 2.7.3 (1381) build. Did anyone get a solution yet? I don't want to reinstall sync on these other computers because I have 10 folders being synced and only 2 of those have this issue. Should I just copy the folders, un-sync them with the other computers, and then re-sync them after?
