Standard Gateway connection for ODBC data source

I have setup Standard Gateway for ODBC data source, and I'm able to see and set Scheduled refresh. Also, I'm able to refresh manually.

But sheduled refresh is getting failed with below mentioned error :

Failure details: Your data gateway is offline or could not be reached. Ensure the computer running the gateway is on during the refresh period.

Is there a way where I don't need my computer to be on at the scheduled time for refresh ?
