power bi refresh error

Hello guys! I have scheduled refresh for my dataset every 1 hour in a premium capacity workspace. Sometimes refersh fails sometimes it is succcessfull. Coudn't figure out the reason for the error:
I'm connecting to my data source using AWS Athena.

Is this a connectivity issue between power bi and gateway?
