I had turned on the diagnostic logging to try to self diagnose more from both ends. My computer and the server had eventually gotten to the point where they were communicating to some degree with pings, but it was never syncing. I had solved the issue by re-installing Sync on my windows computer. No setting seems to be different, so I'm guessing the installation must have gotten corrupted in some form.
Hello! I have had BTSync running on a linux x64 server on version 1.3.89 for a while without any noticeable issues, but with version 1.3.94 it only complains it "Could not map UPnP Port on this pass". I'm running it on shared servers so I need to change the ports, but I haven't noticed any issues up until now, but have had this issue as of late on 2 different servers. sync.logbtsync.conf
