Firewalls disabled, replication worked fine, IP's accessible..

As soon I try to restart the first node it won't reconnect.
I cannot restart the whole cluster as it supposed to be serving content 24/7 with at least 3 nodes available at all times...
Any idea how I can setup Galera so it would survive a restart of ANY node? (restart of a cluster is a pretty much fatal crash as leads to losses going in xx k of $ and the main reason behind selecting Galera was the low cost vs Microsoft (which can survive without a problem any number of resets while setup correctly)...
As I am trying to push Galera instead of Windows, I have to prove that indeed it is a commercially viable solution (which means that it have to survive main node restart, especially that we have dozens of "main" servers so "first" node is strictly theoretical).
I was testing in ~ 2 weeks ago and unfortunately, it ended up with a restart and data loss (due to having test servers offline)
