MP4 files won't play. ".mp4 files are supported but something went wrong."

So I've been uploading videos to dropbox and suddenly dropbox just stopped allowing me to view the videos on the site. My other videos play fine but the ones I upload now just won't play. Anyone know the cause for this?

    Hi NoMoreGrid, sorry to hear that. 
     
    Could you please try one of the following steps and see if that does the trick?
    • Try previewing the video from another browser. 
    • Navigate to the video preview through an incognito/private browser.
    • Ensure that you’re not running any third party browser extensions. 
    • Clear the cache. 
    If you’re still having trouble with this, I can send you a ticket to the email address associated with your Community profile so as to have a more in-depth look on this. 
     
    Let me know how it goes!

    This message keeps popping up on my chromebook, "mp4 files are supported but something went wrong." Then when I try to download, I get an error message.

      Hey PDFFILESSUPPORT, thanks for reaching out to us about this. 

       

      I moved your post to this thread where other users have expressed a similar behavior. 

       

      Just to make sure that I have a better understanding of your concern, could you please let me know:

      • What error message do you get when you try to download the files? Could you send me a screenshot of it?
      • Do you see this preview error message with all .mp4 files or specific ones?
      • Have you tried previewing or downloading the files that have this issue from another browser?

      Let me know what you find - thanks!

    Having same problem.  Trying to share an mp4 file - as I have done on multiple occasions before - now all recipients getting the  "mp4 files are supported but something went wrong" message. I also get the message if trying to watch through a browser. This is clearly a common error. Sort it out Dropbox.
