A number of the API calls are working fine, but `RespondDecisionTaskCompleted` fails - I get `FailedConnectionException` errors:\r\n\r\n```\r\n[Amazonka Env] {\r\n  region      = us-east-1\r\n  retry (n=0) = Nothing\r\n  [Amazonka Auth] {\r\n    access key     = ####\r\n    secret key     = ****\r\n    security token = Nothing\r\n    expiry         = Nothing\r\n  }\r\n}\r\n[Client Request] {\r\n  host              = swf.us-east-1.amazonaws.com\r\n  port              = 443\r\n  secure            = True\r\n  headers           = authorization: AWS4-HMAC-SHA256 Credential=####/20151008/us-east-1/swf/aws4_request, SignedHeaders=content-type;host;x-amz-date;x-amz-target, Signature=$$$$; content-type: application/x-amz-json-1.0; host: swf.us-east-1.amazonaws.com; x-amz-date: 20151008T061529Z; x-amz-target: SimpleWorkflowService.RespondDecisionTaskCompleted\r\n  path              = /\r\n  query             = ?\r\n  method            = POST\r\n  redirect count    = 10\r\n  response timeout  = Just -3425\r\n  request version   = HTTP/1.1\r\n}\r\n[Retrying] after 1 attempts.\r\nHttpError (FailedConnectionException \"swf.us-east-1.amazonaws.com\" 443)\r\n```\r\n\r\nI'm now in the process of trying to update to newer amazonka builds (`1.3.2`), but was curious if there might be a quick answer here around why only one of the API's is failing so far.\r\n\r\nDefinitely close this out if this is from too old stuff :)"}}
