The first error is telling you that au.thethings.network doesn’t exist, and there doesn’t seem to be a DNS record for it. Are you sure it’s not meant to be au.cloud.thethings.network as that follows their usual naming pattern. 

Hello thank you for your response , yes it is provided by the repo owner in the documentation

Based on https://www.thethingsindustries.com/docs/getting-started/cli/configuring-cli/ and your error, you should use au1.cloud.thethings.network instead.

hello thank you it did change the error to this
