    Dropbox files can't be downloaded

    Asked by featurette on February 12, 2013 at 02:49 PM

    My dropbox integration is inconsistent. File sizes are typically large, around 300 mb. 8 of 10 file submissions have been successful, but two result in an xml error when download is attempted. I also relate ths issue with an unknown glyph that preceeds the link from either the pdf or my form "inbox" on jotform.com. The glyph is displayed on my mac as a ? but I cant tell if it is apart of the link or just coincidence. Either way, successful files do not have this glyph artifact.

    For a dropbox integration , we recommend you to upload file no more than 300MB, 150-300 MB is the recommended one

    On regards to downloading the file from your submissions page, that should be an isolated issue. I have cleared your forms cache in our side. Please clear your browser cache if let us know if the issue still persist.

    At any rate, we are currently having an issue with our dropbox integration that will not show the thank you page properly  , but it is already taken care by our developers .

    The issue still persists and is independent of the browser. Successful uploads are easily recovered from my jotform inbox and sync directly in my dropbox folder. I don't know the file sizes of the failed uploads but I have received files over 1 gb just 2 weeks ago. 

    I realize there are many factors at play but the jotform url that is created from these failed uploads has a formatting error that can be reproduced.

    That blue ? is in front of the two failed urls.

    I just consulted to our Cheif Technology Officer and he confirmed to me that Dropbox has a limitation with files over their API. (150MB per file), therefore , we can not increase it

    So, just make sure your users will not upload bigger files. My recommendation for you would be to try gdrive integration rather than DBox

    Hi Jeanette,

    I followed your advice about uploading larger files to GDrive and get the same result. I am assuming this is a JotFom issue because I get the same xml error when I attempt to download the file that is stored on your Amazon S3 server. Bummer, I was really hoping to use JotForm for my service.

    Usually, the 'AccessDenied' XML error means that the file was not fully uploaded or it was corrupted during upload. HTTP protocol is not very friendly for large uploads, so that there might be some issues due to user's internet connection, user's browser, and other reasons.

    Also, please make sure that your users do not close the browser until the upload is finished (form Thank You page showed).

    As far as I can see, most of your uploads are fine.

    Thanks Mike, my plan is to limit uploads to 300 mb through jotform. Consider me interested in a product that can reliably handle >300 mb upload forms. Dropbox or GDrive integration isnt as important if I can retrieve file uploads from your aws account. 

    Cheers, Sam
