Hi, I have a problem caused by: sun.security.validator.ValidatorException: PKIX path validation failed: java.security.cert.CertPathValidatorException: Path does not chain with any of the trust anchors I configured 3 node clusters using a token, all 3 nodes worked, however, during tests and turning off node 1, a discover error occurred, after adding the discover host, i.e. the addresses of the remaining nodes, the error changed to the one with the certificate. Currently, clutser after \_cat/nodes shows 2 nodes, but node 1 cannot connect. due to certificate error ---

Can you provide logs and/or configuration? It's hard to diagnose TLS trust issues without a bit more detail. ---
