Question

Problem with Flash file uploading

Specifications:

  • Windows 7 32-bit
  • Firefox 15.0.1, Chromium 22.0.1250.0 and Internet Explorer 7
  • Adobe Flash Player 11.4.402.287

Problem:

Hi everyone.

I'm a frequent user of file hosting services. They usually offer a Flash file uploader to upload your files.

Using the Flash file uploader, I always encountered error and the file will fail to upload.

Example sites that produces the error are SugarSync and Dropbox.

SugarSync simply fails to upload and report it as a failure.

Dropbox reports "Sorry, it looks like the advanced uploader is incompatible with your system. Please use the basic uploader to upload via the website".

The problem happens in both Firefox and Chromium, but not Internet Explorer.

The file uploads without any error in Internet Explorer.

Considering how it happens on two different browsers, I assume that there are no problems with the browsers.

Methods tried:

  • Reinstalled browsers.
  • Turned off Protected Mode in mms.cfg.
  • Fallback to Flash 11.2, 10.3.
  • Downloaded the Flash Player Uninstaller and performed a complete uninstallation. Then reinstalled the latest version of Flash Player.

None of them work, and at the moment, I have the latest Adobe Flash Player.

Thank you in advance for your time and help.

EDIT:

In case you are wondering, there are no problems with Flash games and YouTube videos.

    On my website, I also make use of Flash to upload and for some of my users, it is not working... The server upload servlet is called  but the file sent has a size of 0.

    @lancersupraskyline - Do you have any security software (antivirus/firewall) that might be blocking the network connection?

    @fatpaint - Is this new behavior that your users are seeing?

    This is not new behavior. I have been seeing this problem on my log files for a long time and it is still there.

    The problem happens in my graphic editor af http://Fatpaint.com when inserting an image from the local computer. I had to implement a html uploader as backup because people were complaining. I have not been able to reproduce the error.

    I use Flash 8 actionscript 2.

    My upload servlet get the request from User-agent "Shockwave Flash" but the stream received has no data (length is zero). There is no problem when using the html uploader. I use "org.apache.commons.fileupload" java lib, so it is not a problem with my servlet.
