Hello, suddenly today I am not able to access files in box folders. When I try to look at them in Box Sync in a finder window I get the attached message 

"Your Device couldn't connect to the server. There may be a problem with the server or Network" 

I have no internet issues other than Box so I don't think it's the network. When I try to access files I accesses yesterday at Box.com I get this error message

"We're sorry, the preview didn't load. This Document may be protected." 

The option to download is still there online but nothing happens when I click to download.

Does anyone have a solution to this problem? It worked just fine yesterday so I don't know what is going on.
