Hello,
Recently saw my BP node show Leader: 1 without any blocks being Adopted or Invalid. Ran the below journalctl and received the below.
sudo journalctl --unit=cardano-node | grep -A 2 “NodeIsLeader”

Do this only indicate that the KES is wrong? I previously looked into this and ran
ls -l kes.skey node.cert
This came back with the KES being a minute or two older with the old KES, which in the SPOT KES checker says it may have not be an issue.
Well since the missed block, I rotated my KES and now the KES is younger than the node.cert which would make sense in order or creation. So hopefully this will solve the KES issue, but just wanted to get some insight if there is anything else I should look for or do before the next block.
