I have a file uploader that is supposed to be used to upload video files to my company's website.

At the office, uploads consistently stall out(get stuck at a percentage and never move again, even if I let it sit for hours), or flat out fail.

When I attempt to upload a file from my home Internet connection, I have no issues. This makes me think there is something in our office's network configuration that is contributing to the problem.

I am certain we have enough bandwidth. We have a 20/20 fiber connection at the office. Whereas at home, I only have a 3/3 WISP connection.

Where can I begin looking to troubleshoot the problem? Should I start with the router/firewall? If so, I am not sure which settings I would want to look into.

I noticed that the request headers for the file upload contain the following lines, however, I have no idea how exactly these could be affecting the upload, if at all:

Connection: keep-alive
Content-Length: 155155400
Content-Type: multipart/form-data; boundary=----------GI3cH2Ef1ae0cH2ae0Ij5gL6ae0GI3
Accept: */*
Accept-Encoding: gzip,deflate,sdch

Any help at all is greatly appreciated.

  • Probably someone is ~killing~ dropping the TCP connection, and the client can't reconnect. The headers look normal. Have you tried uploads to different sites? Is it all HTTP uploads, or just one specific server? – David Souther Oct 08 '13 at 14:10
  • What protocol does your file uploader use? What are the upload limitations of your hosting site? – CIA Oct 08 '13 at 16:33

This happens because your file uploader is trying to grab as much bandwidth as possible, and any delay (by a firewall, etc.) can stall it. Limiting the bandwidth to upload the files could help you.

In other hand, my first option will be look at the firewall, routers could have a firewall configured inside, or proxy configuration, maybe you have there some kind of limits about bandwidth.

The "uploads consistently stall out(get stuck at a percentage and never move again" makes me think that there is a timeout occurring. Is the time the upload hangs the same for different files? If yes, I'd immediately suspect something in the router, with NAT timeouts being my first look.
