Hi forum, I have been using btsync for months with no problems. This week though, one computer I use is not syncing with the rest. It's my office computer, so I suspect there is something which might have changed with the network here which is causing the issue. (Though, strangely, when I connect to the wifi network here I *can* sync...) I was running Ubuntu 12.04, and upgraded to 12.10 and that has had no effect. The tail of /var/lib/btsync/sync.log is below: [20140402 14:15:53.579] Using IP address **.**.**.**[20140402 14:15:53.580] Loading config file version 1.3.77[20140402 14:15:54.108] Loaded folder /media/storage/teaching[20140402 14:15:54.109] bind port is 18685[20140402 14:16:18.600] NAT-PMP: Unable to map port with NAT-PMP.[20140402 14:16:53.587] NAT-PMP: Unable to map port with NAT-PMP.So, something is fishy with the port mapping. Any thoughts on how to fix it?
