Marcs Updater

There have been some reports about issues with the Updater not updating anymore. Please try the latest beta version and switch to another IP Check provider instead of the previous default dnsomatic.com. For some reason they are rate-limiting the number of requests to their service. The new IP Check provider selection allows you to choose another provider in such cases. You can test the functionality with the new "Test" panel.

If you want to add a custom provider to the unstable testing version, store a JSON file like the following under %PROGRAMDATA%\Marcs Updater\ServiceProviders\dyndns.json:

    "name": "DynDNS.org (Test)",
    "endpoint": "https://members.dyndns.org/nic/update",
    "method": "GET",
    "queryString": "hostname={HOSTNAME}&myip={MYIP}",
    "dataPayload": "",
    "defaults": {
        "username": "test",
        "password": "test",
        "hostname": "test1.customtest.dyndns.org"

Supported query and payload tags are {USERNAME}, {PASSWORD}, {HOSTNAME} and {MYIP}. Restart the background service and foreground application to apply any changes.

Kinda feel like I must be doing something wrong. I'm having a problem setting up the Updater for OpenDNS. I've used the most recent stable and the beta.

No matter what I put in the username and password fields, I get "badauth" message in the lower right and a Windows notification stating " The username and password do not match a real user. Please check your settings to continue."

I've verified my credentials by logging into OpenDNS dashboard. Am I supposed to be using some other creds? I can't find any documentation for the Updater detailing what the major fields are expecting, so if Username and Password fields are not expecting OpenDNS creds, what are they expecting? Also, what am I supposed to be populating in "Hostname"?

Running latest Windows 10 build (21H2), if that matters.
