Similar issue for me. None of the 1.4.x builds have worked properly for me on readynas. I re-add folders using the secret, it re-indexes the data and then just says "No Peers". I have a Mac and a Windows 8 PC on the same network working fine. Running the latest version 1.4.77 Update - when I setup the folder on the netgear nas using an empty folder it seems to work fine. Ie finds the other peers and syncs the data. Its when I point it at an existing folder that I get the "no peers" issue. And I've tried deleting the .sync folder - same result.
