# DynamicTempoBlockedByCommitReveal (/docs/errors/chain/DynamicTempoBlockedByCommitReveal)

`trigger_epoch` is refused while commit-reveal is enabled on the subnet, because an out-of-band epoch would desync the CRv3 reveal window from the Drand schedule and drop committed weights. Check the `commit_reveal_weights_enabled` hyperparameter; disable it before manually triggering epochs.

Declared by the `SubtensorModule` pallet; it classifies to the semantic code [`disabled`](/docs/errors/disabled).
