Troubleshooting

Can't install? Check whether already installed (e.g. previous version) and restart computer. Must be an Administrator to install.
Error when saving configuration? Check that Windows service is installed.
No updates? Check that service is running. Try using the check and update URLs in your web browser. Turn on verbose logging.
No logs? Check the output directory. Set it to something simple like C:\
Can't uninstall? Set Windows service to 'Disabled' and restart, then try. Must be Administrator.

Understanding how it works

DDNS Updater runs as a Windows service. Changing the configuration restarts the service (including resetting any timers). Beginning with version 0.1.3, DDNS Updater starts in 'warm-up mode' where the check interval is reduced to a few seconds until there is a valid response. This is because Windows may not have an IP address assigned at the time DDNS Updater starts and it may be undesirable to wait the full check interval (e.g. 10 minutes) if an initial failure occurs for that reason. Once the external IP has been successfully detected, the service reverts to the regular check interval.

DDNS Updater has a built-in list of check URLs. Because these URLs may stop working without warning, DDNS Updater cycles through until it finds a live one. This improves robustness but can make the initial DDNS update slower if the buit-in list contains several bad URLs. Configuring a specific check URL disables the buit-in list. Creating your own private check URL on a web hosting provider is easy, e.g. in PHP:

<?php if(isset($_SERVER['REMOTE_ADDR'])) { echo $_SERVER['REMOTE_ADDR']; } ?>
