Unable to start elasticsearch cluster

[jlinesnm]

I am working on setting up an elasticsearch cluster for a Wazuh project. I have been following the steps from the Wazuh documentation: https://documentation.wazuh.com/current/installation-guide/open-distro/distributed-deployment/step-by-step-installation/elasticsearch-cluster/elasticsearch-multi-node-cluster.html#elasticsearch-multi-node-cluster. I am setting up a 3-node cluster: 1 master and 2 data. I have run the following security admin script: export JAVA_HOME=/usr/share/elasticsearch/jdk/ && /usr/share/elasticsearch/plugins/opendistro_security/tools/securityadmin.sh -cd /usr/share/elasticsearch/plugins/opendistro_security/securityconfig/ -icl -nhnv -cacert /etc/elasticsearch/certs/root-ca.pem -cert /etc/elasticsearch/certs/admin.pem -key /etc/elasticsearch/certs/admin-key.pem -h 10.1.8.232. After running it, I received a Green clusterstate, but then I received the following error: FAIL: Configuration for 'actiongroups' failed because of UnavailableShardsException. This error repeated for several different groups, then the script ended with: ERR: cannot upload configuration, see errors above. I'm not sure what I need to do to fix this. Any help would be appreciated.

Thanks.
