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

This is the second time I have gotten this message from a file that my instructor shared. Last time was a couple weeks ago and it started working after trying a few things.

Today I'm having the same issue with a different recording shared by the same instructor. I was 1 hour and 50 minutes into a 2 hour video with no issues and then I get this message. I have cleared my cache, tried several different browsers and troubleshooted what I can think of to no avail. I get the same message on a different computer as well. It won't let me download the file either.

Not sure what is going on but it's very frustrating! Any fixes figured out in the last 6 years since the last topic on this was posted??

    You will need to because that sounds almost certainly like its the issue. 

    Or, you need to download the whole file locally and play it that way - which will not have the limitations of the web play back on it

    The error is in my post title above. I don’t know the file size as I can’t access it and I can’t speak to my instructor directly.

    Hey runruh1981, welcome to our Community. 

    First off, can you clarify the total size of the video you’re previewing? What other troubleshooting steps have you already tried?

    I’d also like to know what’s the type of Dropbox account your instructor has, since there can be a few limitations based on it. 

    Feel free to send me a screenshot of the error you keep receiving, as well. 

    Ping me once you have more info.
