Comment 2 Archit Modi 2017-10-30 16:59:11 UTC

Created attachment 1345544 [details]
Steps to configure ec2api service

Comment 3 Sven Anderson 2017-11-03 14:36:56 UTC

Most probably this is not an EC2 API issue, but haproxy is running on the port instead but not configured properly. Can you check?

Comment 4 Sven Anderson 2017-11-03 16:54:15 UTC

The problem is, that haproxy does a healthcheck that expects a 200 OK response. EC2-API however returns 400, if not authenticated. I submitted a fix upstream.
