CloudWatch cn-northwest-1 region issue

We have a CloudWatch datasource that is working just fine in almost all regions except for two

  • cn-north-1
  • cn-northwest-1

On the AWS/ECS namespace for those two regions (which have ecs’s in them), we’re getting an error:
http: proxy error: net/http: HTTP/1.x transport connection broken: malformed HTTP response "\x15\x03\x03\x00\x02\x02P"

We can get metrics from other namespaces in that region, and the AWS/ECS namespace works in other regions on the same account (us-east-1, eu-central-1, etc.)

This was tested on grafana 6.2.5 & 6.6.2
