As Hans said, this might reguire a change in the proxy server configuration as discussed here: http://gmod.827538.n3.nabble.com/Data-uploaded-with-new-upload-tool-doesn-t-get-added-to-history-td4046375.html

Hi Bongsoo

we had once a similar situation with one of our development Galaxy installations. This was due to a change in the proxy settings of the server.

Aysam,

Thanks for your reply. It works well on usegalaxy.org
<http://usegalaxy.org>, but it doesn't work in the Galaxy instance I've
developed. I downloaded the latest Galaxy version, and installed on the
Redhat 6.5 system. I created a galaxy user, and just ran it as usual. I
have to update any part of the configuration? I have to allow any
specific port to use file upload function? Thanks!

Best,
Bongsoo

    Does this happen on usegalaxy.org <http://usegalaxy.org>? Also does
    this happen with other files too?

    Thanks,

        Hi folks,

        I encountered the problem in file upload. The error message is
        like below
        'Failed: Not found (404)'. Attached is the screen shot for this
        error message. Any idea? Thanks!

        Best,
        Bongsoo
