As @legoguy1000 already said, the configuration file (with secrets or sensitive information redacted) is probably essential to understand what's going on.
From your error message, I see that the hostname logs.ap-southeast-2.ap-southeast-2.console.aws.amazon.com does not exist.
According to the Amazon CloudWatch Logs endpoints and quotas page, the endpoint for the region ap-southeast-2 is a little different: have you customized the endpoint?
