I have a problem with joining a node to a cluster after total shutdown.
I started first node as bootstrap, looks OK.
But second node didn’t start. I see following in log:

You have network issues. Ensure all proper ports are open between all nodes. Use `ss` or `nc` or `telnet` to verify you can connect to all nodes, from all nodes on 3306, 4444, 4567, 4568.
Also, because PXC 8 is SSL by default, ensure you have copied the SSL certificates from the bootstrap node to the other nodes before joining them. All nodes must use the same SSL certs.
