Hazelcast will not start on either server

Openfire Plugins

@@Tom Evans

Hey Tom, maybe you can help. I’ve had the Hazelcast Clustering plugin working for a while. I recently upgraded Openfire from 3.10.3 to 4.0.2 and at some point last night I had to force OpenFire to shut down via task manager on Windows 2012 R2. The server would not stop when I tried to make it stop, so I had to kill the task manually. Ever since then, I cannot get the Hazelcast plugin to work. I get it installed on both servers and when I try to enable it and click save, it just sits there thinking and thinking and never does anything. \

I tried removing the plugin and then reinstalling it on both servers but this keeps happening.

My LAN IPs match what the default config file is set to use: 10.10.1.10 and 10.10.1.11 for those 2 servers. I also tried editing that file and making the following changes:

<tcp-ip enabled="true">

          
  <member>10.10.1.10:5701</member>

          
  <member>10.10.1.11:5701</member>
</tcp-ip>

<aws enabled="false"/>

10.10.1.*

I just removed the Hazelcast plugin and then installed it. Then I restarted the OpenFire service. I did not set it to enabled yet, I only installed the plugin.

I went to User Summary and got this error:

HTTP ERROR 500

UPDATE: This appears to only have these issues when the plugin OFMEET is being used. When I remove OFMEET, then it works without any issues.
