Resolver IService Refresh Constant Errors
Follow up: Yes, we always use the latest gateway and we have gone through and load balanced our refresh schedule. As of last week the machine hosting the On-premises Data gateway was pegged. Our engineers have moved from a B Series VM to a D series VM. This move has proved to be very successful and refresh failures dropped dramatically. Next step we will either add additional gateways or move to a VNet Gateway.
Thanks all for the responses. FYI running F32 capacity.

You're definitely not alone, I've seen more discussions around intermittent refresh failures this year than in previous releases. That said, I'd first try to determine whether the failures are service-related or model/data source-related rather than assuming it's the Power BI version itself.
A few things that have helped:
- Check the Refresh history for patterns (same dataset, same time, same error).
Stagger scheduled refreshes so multiple large semantic models aren't competing for capacity at the same time.
- If you're using a gateway, keep it updated and review the gateway logs for intermittent connectivity issues.
- Monitor capacity health (if you're on Fabric/Premium), as throttling or resource contention can lead to seemingly random refresh failures.
Out of curiosity, are your refresh failures mostly gateway timeouts, capacity/resource errors, or are they different every time? That would help narrow down whether the issue is environmental or service-related.
