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...

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!

    Thanks for the screenshot, PDFFILESSUPPORT!

     

    Could you also let me know the error message that comes up when you try to download it? 

     

    Could you also confirm if you've tried previewing the file from another browser and if this happens to all .mp4 files?

      Thanks for the swift reply, PDFFILESSUPPORT. 

       

      Just for troubleshooting purposes, could you try clearing your cache and making sure that you're not running any third party browser extensions or plugins?

       

      Also, could you confirm if these files that you're having trouble with are personal that you uploaded, or files in a shared folder that was shared with you?

      The browsing history is cleared.

      The 3rd party extensions on Chrome being run are Google Docs offline 1.10.0, Google Meet Grid, Google Slides 0.10, Docs 0.10, Sheets 1.2. Also, it is on developer mode.

        Also, when I went to download settings, in Google Chrome, this are the cookies attached to Drop Box.
