This file cannot be previewed because you are offline

As of this morning, this is the fate of any file I try to access: 

I've done the enabling-cookies thing (I use Chrome); nothing. 

I'll try restarting my computer and see what happens. 

My guess is that someone in Dropbox made some "improvement" that is the polar opposite of progress. Please unimprove things!

Doing a system restart seems to have repaired this glitch. Fingers crossed that it will stick. I find that more and more websites have become prisoners of developer-inflicted glitches--making the Internet and personal computing harder to use with ease. Such is the lot of the 21st century.

I had this strange problem with both Firefox and Safari.  Right after I preview any video file (we stored only video file in Dropbox), then the next file I will get the message below.

Even I hit the same file I got the same message.  But then if I refresh the page, everything works again normal but again only once.  Everytime when I preview one file, the next thing came up is Couldn't preview this file unless I refresh again.  I re-start the computer and same result.

Hi joe1shogun, how large is the file you're trying to preview? 

Are you currently logged into your account, or are you trying to view this file via a shared link?

I have been doing the same thing and previewing all the files in Dropbox for at least over one year and never had any problem, so it is not a matter of file size or anything else.  I am trying to preview all files in Dropbox and there is no exception.  All files I can preview only once, and then I need to refresh otherwise I will get the same message....Cannot preview... with the stup.. guy looking at the teles....

Is this occurring with any person that accesses the files, in any location or network?

Do you have any proxy, VPN, firewall, security software, or even ISP/router issues could be restricting traffic to the following Dropbox domains?

I am also having the same issue and cannot send the files to my clients. 

I've disabled the firewall, the antivirus software, downloaded the app instead of using via the website... nothing and Im getting super desperate. 

Hi lindamarea, how are you today? 

How are you trying to preview content? Do you access using the website, or the app?

Feel free to also send me a screenshot, so I can have visual. 

Thanks!

Hi Megan

via both. 

Thanks for the screenshot, lindamarea! 

Have you by any chance tried a different WiFi network, just to notice if the behavior will remain the same?
