I don't know what the problem is/was but I've tried again today and its working ok, this is annoying, I hope it stays okay now. I haven't changed any settings over the past few days. EDIT: I spoke too soon, it'd now not working, so I done a few tests, when I try to a) use btsync b.) query port 3000 and c) download that link you said to, they either all work together or all fail together, it would seem my mobile internet provider is blocking traffic intermittently for no apparent reason. How annoying, I'll have to speak to them about this.
