Troubleshooting Firehose endpoint reachability

If the Firehose API encounters a timeout, perform the following steps to test endpoint reachability:

  • Check if API requests are made from a host in a VPC. All traffic from a VPC requires setting up a Firehose VPC endpoint. For more information, see Using Firehose with Amazon PrivateLink.

  • If traffic is coming from a public network or VPC with the Firehose VPC endpoint set up in a particular subnet, run the following commands from the host to check network connectivity. The Firehose endpoint can be found at Firehose endpoints and quotas.

    • Use tools like traceroute or tcping to check if the network setup is correct. If that fails, check your network setting:

      For example:

      traceroute firehose.us-east-2.amazonaws.com

      or

      tcping firehose.us-east-2.amazonaws.com 443

    • If it appears the network setting is correct and the following command fails, check whether the Amazon CA (Certficate Authority) is in the trust chain.

      For example:

      curl firehose.us-east-2.amazonaws.com

    If the above commands succeed, try the API again to see if there is a response returned from the API.
