Do you have any antivirus software running on your Host machine? It seems like the issue might be occurring because something is forcibly interrupting the connection, which might be a part of some antivirus software activity. Please try adding the Host installation folder C:\Program Files (x86)\Remote Utilities - Host\
to the a/v software exceptions list as described in this guide
. After adding the folder to the exceptions, please make sure to restart your Host machine.
Let us know if this helps to resolve the issue.
