In my case, not even shuting down se 'server1' makes it work.
Here is the log of server1:

The only way to work was to switch off (init 0) the primary and it worked,
keactrl stop only doesn't work it gives connect refused and not no route to
host, that's the only difference.

With a similar config (basically the same), I am facing the same situation on
1.6.2. Anyone care to point out some obvios configs that we might be missing?
