How to solve "Registry.rebind disallowed" exception when setting ehcache.listener.hostName

[domruf]

I'm trying to setup Jira data center (version 8.16.1).

At first it looked fine. I created 2 nodes and I saw them on /plugins/servlet/cluster-monitoring

But I noticed the cluster addresses looked like dd72fc5dbc03:40001, where dd72fc5dbc03 is the docker internal hostname. Since these addresses are not reachable by the other nodes I also got "UnknownHostException: dd72fc5dbc03" error messages in the log output of the other node.

So I added

ehcache.listener.hostName = myrealhostname

to the cluster.properties file. But now I get errors like this

2021-09-10 10:35:11,432+0000 localhost-startStop-1 ERROR [c.a.jira.startup.ComponentContainerLauncher] A fatal error occurred during initialisation. JIRA has been locked.
net.sf.ehcache.CacheException: Problem starting listener for RMICachePeer //myserver.mydomain.net:40001/com.atlassian.jira.crowd.embedded.ofbiz.EagerOfBizUserCache.userCache. Initial cause was RemoteException occurred in server thread; nested exception is:

at net.sf.ehcache.event.CacheManagerEventListenerRegistry.notifyCacheAdded(CacheManagerEventListenerRegistry.java:159)
...

 And now the Jira node is not even starting anymore.

If I remove ehcache.listener.hostName, Jira is starting again.

Hello @domruf 

Welcome to Atlassian Community!!

To fix the issue, edit the cluster.properties file and edit/add the following statement on all the nodes.

ehcache.listener.hostName = localhost
ehcache.listener.port = 40001
ehcache.object.port = 40011

Hope, this will fix your issue.
Let me know in case of any further help.

Thanks,

I have updated to 8.18.2 now.

Here, this problem no longer occurs.

But now I get
