I just upgraded Openfire from 3.8.2 to 3.9.3, then upgraded all plugins. After server restart, the cluster stoped working - all nodes now see only themself. I tried many tweaks and spend about a day trying to make it work again, but without success.
I just have 2 nodes on 2 computers, there is no firewall between them.
The configuration is simple:
<hazelcast xsi:schemaLocation=“http://www.hazelcast.com/schema/config hazelcast-config-3.1.xsd”
Is there anybody to whom is tcp based configuration with Hazelcast in 3.9.3 working?
