ServingRateLimitExceeded

serve_axon or serve_prometheus was called again before enough blocks passed since the neuron's last serving update. Check the axon's last update block in Axons against the ServingRateLimit (serving_rate_limit hyperparameter) and wait.

Declared by the SubtensorModule pallet; it classifies to the semantic code rate_limited.

Remediation

Wait for the rate-limit window to pass, then retry

The same explanation is available in the terminal: btcli explain ServingRateLimitExceeded.
