Suddenly dropbox can not link to the web. It says there is no connection. I can open a browser. Is it a firewall setting?
It could be there is a problem on the dropbox server(s), try it again later today.
I have just logged on to my dropbox account without problem - that said I noticed that they have done some modifications to the layout and other behind the scenes activity.
At first it didn’t display my folder layout and others areas are loading slowly.
I don’t know if that may have something to do with the problem you are experiencing.
