Recommended action:
%% if matches!(self.blockchain_state, BlockchainState::Normal) {
Check neptune-core logs to ensure it is operating correctly.
No further corrective action should be necessary.
%% } else {
If only one hour has passed since the last block:
1. It is possible/likely that a block simply has not been found yet.
2. Check neptune-core logs to ensure it is operating correctly.
3. Check other nodes to ensure they are at the same block height.
if two or more hours have passed since the last block:
1. Check neptune-core logs to ensure it is operating correctly.
2. Check other nodes to ensure they are at the same block height.
3. Consider restarting neptune-core
4. Consider filing an issue, or alerting neptune-core developers.
