Are you sure the logs belong to the same stake pool you are querying?

The leader logs is from another server, but I used the vrf file from BP node.

We have also experienced the 'mystery slot' issue on 5 occasions since Cardano's Vasil hard fork.

For example:

     SlotNo                          UTC Time
-------------------------------------------------------------
     76216901                   2022-11-07 01:06:32 UTC

First two were 'mystery slots', but minted the third one:

     SlotNo                          UTC Time

@Robinyo Your issue is unrelated, since your logs show NodeIsLeader for that slot.

CarlosLopezDeLara commented 1 year ago

AFAIK this is solved here: https://github.com/input-output-hk/cardano-node/pull/4106 and is just waiting to be included in 1.36.0
