Logged Error: cardano.node.ErrorPolicy:Error:1360, 2589, etc

My stake pool looks normal but cannot mint a block since the first block 6 months ago…
Try to investigate and I found this error in two relay nodes.
My nodes are up-to-date 1.32.1.

Anyone have experience on similar error?

Hi,

Do u have lost blocks? Because if u have IN/OUT peers and TX processed it should be fine…
What is the total amount staked to your pool?

Cheers,

The IPs x.x.x.x and y.y.y.y are nodes running old versions of cardano-node trying to connect to your node. You can ignore the errors.

Thank you very much. So I don’t have to concern those errors…

Does anyone know a source to learn about those cardano-node error codes?
