Power BI Service Subscription Failure - Intermittent and a single report

Hi TekkyTec 

This is almost always caused by a temporary capacity or rendering failure at the exact time the scheduled subscription runs, not by the report or recipients. Scheduled subscriptions are queued and executed on Microsoft’s backend rendering service, and if that service is throttled, busy, or briefly unavailable for your capacity at that moment, the job can fail without surfacing a UI error, while a manual “Send now” works because it runs on a different on-demand execution path. That’s why your refresh succeeds, permissions look fine, and it fixes itself the next day. There is no tenant-side fix for this — the only real mitigations are move the report to a less congested capacity (PPU or dedicated Premium), shift the send time away from peak hours, or split the subscription so it doesn’t collide with heavy background activity.
