Certificate or Connection errors with AWS servers

CDO is adapting a new way of communicating with the Secure Device Connector (SDC). To facilitate this, CDO must migrate your existing SDC to the new communication method by February 1, 2024.

Note

If your SDC is not migrated by February 1, 2024, CDO will no longer be able to communicate with your devices through the SDC.

CDO's operations team attempted to migrate your SDC but was unsuccessful because they experienced a connection issue.

Please follow the steps below to correct the connection issue. Once this problem is resolved, we will be able to proceed with the migration.

Procedure

Step 1

Create firewall rules that allow outbound proxy connections, on port 443, to the domains in your region:

  • Production tenants in the Australia region:

    • cognito-identity.ap-southeast-2.amazonaws.com

    • cognito-idp.ap-southeast-2.amazonaws.com

    • sns.ap-southeast-2.amazonaws.com

    • sqs.ap-southeast-2.amazonaws.com

  • Production tenants in the India region:

    • cognito-identity.ap-south-1.amazonaws.com

    • cognito-idp.ap-south-1.amazonaws.com

    • sns.ap-south-1.amazonaws.com

    • sqs.ap-south-1.amazonaws.com

  • Production tenants in the US region:

    • cognito-identity.us-west-2.amazonaws.com

    • cognito-idp.us-west-2.amazonaws.com

    • sns.us-west-2.amazonaws.com

    • sqs.us-west-2.amazonaws.com

  • Production tenants in the EU region:

    • cognito-identity.eu-central-1.amazonaws.com

    • cognito-idp.eu-central-1.amazonaws.com

    • sns.eu-central-1.amazonaws.com

    • sqs.eu-central-1.amazonaws.com

  • Production tenants in the APJ region:

    • cognito-identity.ap-northeast-1.amazonaws.com

    • cognito-idp.ap-northeast-1.amazonaws.com

    • sqs.ap-northeast-1.amazonaws.com

    • sns.ap-northeast-1.amazonaws.com

Step 2

You can determine the full list of IP addresses you need to add to your firewall's "allow list" by using one of the commands below.

Note

The commands below are for users that have jq installed. The IP addresses will be displayed in a single list.

  • Production tenants in the US region: 
    curl -s https://ip-ranges.amazonaws.com/ip-ranges.json | jq -r '.prefixes[] | select( (.service == "AMAZON" ) and .region == "us-west-2") | .ip_prefix'
  • Production tenants in the EU region: 
    curl -s https://ip-ranges.amazonaws.com/ip-ranges.json | jq -r '.prefixes[] | select( (.service == "AMAZON" ) and .region == "eu-central-1") | .ip_prefix'
  • Production tenants in the APJ region: 
    curl -s https://ip-ranges.amazonaws.com/ip-ranges.json | jq -r '.prefixes[] | select( (.service == "AMAZON" ) and .region == "ap-northeast-1") | .ip_prefix'
Note
If you don't have jq installed, you can use this shortened version of the command:
curl -s https://ip-ranges.amazonaws.com/ip-ranges.json

What to do next

Contact the Cisco Technical Assistance Center (TAC) once you have completed these steps, or in case you encounter any errors. Once you have successfully completed these steps, the CDO operations team can complete your SDC migration to the new communication method.
