This has never been an ID problem. It's a network problem, in most cases caused by packet loss in the network itself or at ISP or issues with gateway hardware. There are many possible reasons.
What I recommend though is that you try installing the latest beta version https://www.remoteutilities.com/download/beta.php
. In this version we implemented some fixes that can help smooth out small network issues and make the overall performance better.
If you install the Beta, make sure that you do that on both ends, Viewer and
Host, not just the Viewer or the Host.
