Hi, Let's do some serious necromancy here. I just had this exact problem. Turns out that after rebooting all nodes (one at the time of course), the monitor could join perfectly. Why? You tell me. We did not see any traces of the ip address in any dumps that we could get a hold of. I restarted all ceph-mgr beforehand as well.

As last resort we've change ipaddr of this host, and mon successfully joined to quorum. When revert ipaddr back - mon can't join, we think there something on switch side or on old mon's side. From old mon's I was checked new mon process connectivity via telnet - all works It's good to make a some reproducer of this network problem to know what exactly message of ceph protocol is broken
