By increasing the Timeout, AWS CloudFormation will wait longer for the ResourceSignal, giving the resource more time to become available and signaling that it is ready. This can help prevent the stack creation from failing due to a premature timeout. PT5M -> 5 minutes also add, cfn-signal with exit code etc. in userdata /opt/aws/bin/cfn-signal -e $? --stack <stack name> --resource <resource name>
