[Maria-discuss] SST's TLS in Galera prevents bootstrapping a new cluster

Hi guys. It's pretty strange, in fact so strange that I presume I must be messing up something rather that MariaDB/Galera behaving this way by design. Thus before I paste any log snippets this question first: Why having this - [sst] tkey = /etc/my.cnf.d/certs/sst/sst.key tcert = /etc/my.cnf.d/certs/sst/sst.crt - would prevent a user to bootstrap new cluster? If do not use tkey/tcert I can bootstrap fine and after, cluster is up & running I put those back, then very next restart of mariadb on any/each node will work just fine. What is happening there some expert would mind to shed more light? many thanks, L.
