Hi Martin,

Thanks for having a look.

I’m now using a Secret Access Key that doesn’t include any punctuation (it took a few key creations to get one like that). But even with that, my videos wouldn’t check out last night.

This evening with my testing, I HAVE been able to get the video to CHECK properly as long as “Select the region” is the Region selection, with and without spaces or +’s in the file name / url. (YAY!) It doesn’t work if I have Oregon (my actual region) selected.

It’s interesting that it’s the region causing the issue, but there’s no more “signature does not match” error when “Select the region” is the option.

For now, this seems to resolve my issue.

Choose “Select a Region” in the FV WordPress Flowplayer > Amazong S3 Protected Content settings.

Thank you for your help!
