Scheduled refresh does not work, but manually Refresh Now works fine

Hi Power Bi Community,

Greetings for the Day!

We are facing an issue where suddenly all power bi Refresh schedules started failing and error code is 'DM_GWPipeline_Client_GatewayUnreachable'. (please find the image below)
We have fixed Gateway issue and for mannually on 'Refresh Now' button data refresh is successfull every time.

But its continuosly failing for Scheduled Refreshes for the same reason.

FYI, we have hourly refreshes schedules.

Please help me if anyone knows about this issue.
Thank you in advance!

Regards,

Abhishek Pednekar.
