Upload works in all browsers on all platforms except for Linux. My site uses a GoDaddy Wildcard certificate. If I disable SSL, the upload works on Linux.
Enabling debug mode for SWFUpload shows the file uploads successfully, even though the HTTP log file on the server shows no POSTs to my upload handler.
Why would SWFUpload silently fail to upload on Linux with Wildcard SSL certificate?

In case anyone else has this problem. The issue is that Flash does not trust the certificate. You must append the bundle.crt from GoDaddy to your server SSL cert to fix that.
See "SSL certifcate chains" in the below document.

I happen to be using nginx, so this document was my solution.
I have no clue why no error was reported... *shrug*
