Hello,
Thank you for your message.
It seems like the issue might be caused by something (perhaps, firewall, or antivirus software, or even your router) interfering with the traffic and causing disconnects. Could you please make sure to add Remote Utilities installation folders to the exception list of any a/v or firewall software you might be using as described
here and if this might help to resolve the issue.
In addition, please check if your router or perimeter firewall have any restrictions or might be blocking any traffic.
Let us know if this helps.
