    Hii nandic 

     

    This doesn’t look like a Redshift or network issue because your Desktop refresh is always fast. Since the delays started only in November and happen only in the Power BI Service, it’s most likely a Service-side capacity/load issue on your F128 backend. We’ve seen similar cases where refresh time jumps from 2–3 minutes to 30+ minutes without any model changes.
    Try checking capacity metrics, moving the refresh to a quieter time, or running Diagnose Refresh to confirm where the slowdown occurs  but the root cause is almost certainly on the Power BI Service side, not your data source.
