I have two peers sychronised by SyncApp. Today I ran into strange problem - I've moved a bunch of files on one peer (WORKSTATION, running Windows 7) and these files (some 507 Mb) are not replicated to HOMESERVER. However these 507 Mb are shown as pending (screenshot 1). Transfer tab shows some attempts to send files, but with no luck (screenshot 2). Debug logs on remote peer (HOMESERVER, running Ubuntu) once in a while shows strange entry: [20130304 15:26:23] SyncFilesController: Got 0 files from remote (94.25.124.150:11821), remote time is 1365049576, request delay: 1 There is NAT with manual port forwarding on both sides. I tried to restart both peers, checked network connectivity but no luck, those 507 Mb are still not replicated.
