Problem to create/launch a new Agent Cloud Agent at Amazon AWS EC2

My issue is that I wish to create a new Cloud Agent configuration but I get errors from Teamcity.

If I use an old configuration under Cloud profile settings can be specified on the configuration page.
and press Check connection / Fetch parameter valuesI get this error

Failed to fetch data from region eu-central-1

URL: ec2.eu-central-1.amazonaws.com

AWS was not able to validate the provided access credentials (Service: AmazonEC2; Status Code: 401; Error Code: AuthFailure; Request ID: 8926036c-4e3e-49f7-823e-f25d76b80c03)

If I create a new profile I get 'Failed to connect to Amazon EC2. Check your credentials' when pressing Check connection / Fetch parameter values

Nothing changed with Amazon IAM profile but it looks like there is changes at Amazon. We use Amazon eu-west-1a and I have seen that Amazon added a new EU zone frankfurt. Logs says something interesting.

I use UTC on all my servers do I need to install Joda-time to fix this or should something be updated with Teamcity? Java version I'm using 1.7.71
