Thanks for letting me know, @Robin130.
Since the file plays normally on another browser, I'd recommend carrying out a few browser-specific troubleshooting steps, such as ensuring that your browser is up to date and not running any third party plugins or extensions.
I understand that this may not be the ideal reply you were looking for but let me know how it goes and if you have any other questions.
Thanks for keeping me in the loop, @Robin130.
Out of curiosity, did you install/run Flash Player? Did you see a change in behavior by any chance?
Let me know of any updates!
Hey @Anjaly, thanks for nudging us here and sorry to hear that you're also having trouble previewing your .mp4 files.
Since you've already troubleshooted a bit - awesome work by the way - I've followed up with a ticket so that we can have a look into this.
Please check your inbox for my message and we'll take it from there. Cheers!
I have the same problem ... as this seems to be a known problem and has been affecting people for years, why is it not being sorted out?
I've been sending video files via Dropbox for 7 years, then today, out of the blue, everything I send to any customer fails with this error! Every customer has their own IT stuff, so this is affecting every browser, not just my end but everywhere, so no point whatsoever in trying to troubleshoot this end.
Hi @jenny14, thanks for nudging us on this thread and I'm sorry to hear that you've recently been having this issue as well.
Although a lot of users have reported the same behavior, it may require account-specific info to be able to troubleshoot efficiently for each case.
For this reason, if you'd like us to have a better look into this with you, you can contact our Support team, or I can send you a ticket if you prefer.
Let me know how you'd like to proceed and I'll make sure to get back to you as soon as possible. Thanks again!
Hey @Netnet22, thanks for reaching out to us on this thread.
Since you mention that you've checked all the steps outlined on this thread - awesome work by the way! - could you also let me know if the file previews normally when you download and open it locally on your device?
Keep me posted - thanks!
