I had this problem a few years ago. I honestly don't remember, but I don't think Netgear actually did anything...I just gave up and then at some point, it started working.

SImilar error here.

Today it rears it's head again after trying to add a new folder to sync to Dropbox and now the sync is totally broken again. It's not that just the new local folder I was trying to push to Dropbox (local upload only is the mode I'm using), but all the existing folders that were syncing have now stopped syncing as well. 

Anyone know a way around this error?
