This article applies to Confluence Data Center 5.6 or later.
Unable to start the Confluence Data Center node or Synchrony, with the following error in the
java.lang.RuntimeException: Hazelcast CANNOT start on this node. No matching network interface found. Interface matching must be either disabled or updated in the hazelcast.xml config file. at com.hazelcast.instance.DefaultAddressPicker.pickAddress(DefaultAddressPicker.java:180)
If you are using Docker, see the following article for that issue: Interface IP is incorrect and not found while starting Hazelcast in a dockerized environment for Confluence Data Center
Wrong network interface set in
<Confluence local home>/confluence.cfg.xml:
- Download list-interfaces.jar from - CONFSERVER-10979Getting issue details... STATUS onto your Confluence node
java -jar list-interfaces.jar
Identify the interface name for that node that matches to the Confluence node IP address, in this example it is en0 that matches 192.168.0.1 (my sample Confluence Node IP):
% java -jar list-interfaces.jar interfaces.size() = 2 networkInterface = name:en0 (en0) ([/fe80:0:0:0:105a:1ff1:8033:4968%en0/64 [null], /192.168.0.1/24 [/220.127.116.11]]) networkInterface = name:lo0 (lo0) ([/fe80:0:0:0:0:0:0:1%lo0/64 [null], /0:0:0:0:0:0:0:1/128 [null], /169.254.169.254/8 [null], /127.0.0.1/8 [null]])
- Shutdown Confluence
Modify or add the following interface line in
<Confluence local home>/confluence.cfg.xmlto match what was returned by the list-interfaces.jar command:
- Start the Confluence DC node
- Once the node has fully started, repeat the above steps on the remaining Confluence DC nodes
Notice some nodes may have a different interface name. Inspect the output of the command on all of them and set the name accordingly.
