This power saver option causes Windward Data to disconnects if the machine is left idle for a long time. This should be disabled to avoid such a problem.

To disable this option on Windows 10 Go to Control Panel –> Network and Internet –>Network Sharing Center–> Change Adapter Settings–> Choose your connection-In my case I have a wireless connection (Right-Click then Properties)–>Click Configure to open NIC Properties–> Go to Power Management Tab and uncheck “Allow the computer to turn off to save power”. See the image below.

Along with this setting, its a good idea to verify the power setting as well.

Go to Control Panel–>System and Security–> Power Options–> Edit Plan Settings –> Set “Turn Off the display” and “Put the computer to sleep” option to Never–> left click on Change advanced power settings–> Set “Turn Off Hard Disks” option to Never and left click on Apply button.  See the image below.
