Suddenly can't upload to amazon s3

Sometime in the last week or two something changed so that I cannot upload files from either the backend or frontend to Amazon S3.

File will be uploaded to: http://s3-.amazonaws.com/vbcoregon.org/

Notice that there is an s3- in front of .amazonaws.com. I'm located in the U.S.

The last sermon successfully uploaded was April 19, 2014.

I'm running ubuntu 12.04 on an amazon ec2 powered server. I have made no major changes other than routine security updates to the OS. I'm using nginx as a webserver. My Joomla version is 2.519 and I'm using sermonspeaker 4.5.8

Thanks for taking a look at this. Please let me know if there is anymore information I can give you.

Check your bucket name and make sure it's a valid bucket. Maybe try without a dot in the name.

Thank you. Removing the dot fixed. Strange that it had been working with the dot for quite a while.

I guess the US region historically allowed more characters in the bucket name and Amazon may have changed that recently. But I don't really know
