I'm developing an integration between Aws Chime SDK and a Ruby on Rails web application, using the official aws ruby client. First of all, I try to create a Aws::ChimeSDKMeetings::Client passing my credentials and a valid aws region like "eu-south-1" to the constructor. However when I try to call a method like create_meeting on the created object, the method fails with Seahorse::Client::NetworkingError (Failed to open TCP connection to meetings-chime.eu-south-1.amazonaws.com:443 (getaddrinfo: Name or service not known)), even if the region I provided is listed as an available media region. If I try to change the region with which I create the client object to "us-east-1", it works properly. I made some attempts and I found that the client works only if it is created within "us-east-1" or "us-west-2" as ragion.

Can someone tell me why it doesn't work with other regions? As long as I searched, I found nothing about it in the official Aws documentation.

There are a few points to mention here while working with AWS Chime SDK:

  • Region that you provide to ChimeSDKMeetings client is the control region, underlying AWS SDK is going to call to. There are 4 control regions that you can provide to Client: us-east-1, us-west-2, eu-central-1 and ap-southeast-1.
  • MediaRegion is provided to CreateMeeting command, that can be any of the regions that are listed in the documentation.
  • eu-south-1 region may not be enabled in your account. Go to Account and check AWS Regions section to check it out.

  • Thank you very much for your answer! ‘eu-south-1’ is enabled for my account. I supposed it was a matter of availability of the control region, but I wasn’t able to find a list of the available control regions, so I though they where the same as the media regions. – Mr5he11 Jun 18 '22 at 08:41
