If you are having issues with the execution of this application, start by enabling verbose logging with the
-v parameter. If you are trying to resolve an issue while running this in cron or as a service, logging is enabled by default to the file
/var/tmp/r53-ddns.log which is a file that should be writable whichever user you are sunning the application under.
If the issues are not obvious or you think there is a bug, please raise an issue via GitHub.
