I'm not sure what cause it

The report points to internal/pkg/reproxy/server.go:347-348 and :559, and internal/pkg/reproxy/action.go:91; start by tracing the DeadlineExceeded and RST_STREAM path from those entries into the remote-apis SDK calls shown in the stack trace. Reproduce or isolate the retry-budget failure, then identify its cause and verify that remote execution no longer falls back unexpectedly or that the failure is diagnosed clearly.
