[Plugin: W3 Total Cache] Request Failed when uploading to Cloudfront

Good morning.

Just installed W3 Total Cache on a custom install from SVN on my Ubuntu box. have all my settings enabled, but when i click the test upload to CloudFront, it stays on “Testing…” and never changes… when i click the “upload includes” button, and select upload, it takes a few seconds and then shows “request failed… waiting 10 seconds” and continues doing this.

I have checked my settings multiple times, and still nothing. Is there a log file somewhere to indicate what is going wrong? it would be nice to get a message other than “request failed”…

Thanks.
