I can't seem to update one of my ddns records: quack.dynu.com

Everything seems to work from my client, but the ip isn't updated. Also, there are no icons under "Actions" on the https://www.dynu.com/en-US/ControlPanel/DDNS page.

Thanks,
Mark

Check if you had a membership and expired. The hostnames out of the free limit cannot be edited if the membership expires. You probably figured this out already. In case it helps other viewers.
