Hello,
Thank you for your message.
Could you please clarify if the remote Host machine stays on after the Host was restarted and the connection to the machine was successfully established? Or if the remote machine is off, for example, at nights?
Also, could you please check if the Host's
Startup mode is set to
Auto or
Manual? In order to check it, please right-click on the Host icon in the system tray and select
Settings for Host, then navigate to the
Service state tab:

If the Startup mode is set to Manual, please try switching it to
Auto.
In addition, please double-check if the Host service is running on the remote Host machine when the issue occurs?

If the Host service is not running on the remote machine at the moment when the issue occurs, please try referring to
this troubleshooting guide before we can proceed to further troubleshooting.
Please let me know if the issue persists.
