As you are using a self-signed certificate, have you placed the CA certificate to /etc/eventstore/certs/ca on all the nodes?

If you used our certificate generation tool, you should have one CA certificate and three node certificates (btw you can use the same node certificate file on all the nodes). It won’t work if each node uses a different CA certificate.

Thanks support. I fixed this problem.
