New node is not able to join the cluster

This set up is for the 3 node cluster on a single box. After starting the first node, while trying to start the second node, it is failing with the below error.

2020-05-05T09:17:03.102658Z 0 [System] [MY-010116] [Server] /usr/sbin/mysqld (mysqld 8.0.18-9) starting as process 2986482020-05-05T09:17:03.107869Z 0 [ERROR] [MY-000000] [WSREP] New joining cluster node didn’t find needed SSL artifacts2020-05-05T09:17:03.108021Z 0 [ERROR] [MY-010119] [Server] Aborting2020-05-05T09:17:03.108368Z 0 [System] [MY-010910] [Server] /usr/sbin/mysqld: Shutdown complete (mysqld 8.0.18-9)  Percona XtraDB Cluster (GPL), Release rel9, Revision 6490e00, WSREP version 26.4.3.

Tried by setting “pxc-encrypt-cluster-traffic=ON” on all the three configuration files but still, the node is not able to join the cluster.  No errors logged on the donor node error log.

Any suggestions, please


Copy the SSL certificates from the bootstrapped instance’s directory to the other two instance’s directory. Then start the other two nodes normally. Alternatively, bootstrap the first node with pxc-encrypt-cluster-traffic=OFF (for testing purposes only), then also disable on each instance before starting them.
