Problem	Solution
The Metrics UI does not display and exceptions are reported in the log file, similar to the following message: `CWPKI0022E: SSL HANDSHAKE FAILURE: A signer with SubjectDN "CN=elasticsearch-http, OU=ICES, O=IBM, C=US" was sent from target host:port "es-metrics.mulvm.ie.ibm.com:9200". The signer may need to be added to local trust store "D:/IBM/WebSphere/elasticsearch-metrics.p12" located in SSL configuration alias "ESCloudSSLSettings" loaded from SSL configuration file "security.xml".`	Verify that the provided trust store .p12 file was updated and copied to all Connection nodes correctly, as described in Configuring the Metrics SSL settings for Elasticsearch.
ES logs report "dangling index" warning messages, lsimilar to the following : `[2018-10-05T12:33:32,647][WARN][o.e.g.DanglingIndicesState][es-data-2][[comppackk8s-haproxy-2018.11.01/sJsYY3KQStmc-lDDb5td8A]]can not be imported as a dangling index, as index with same name already exists in cluster metadata [2018-10-05T12:33:32,647][WARN][o.e.g.DanglingIndicesState][es-data-2][[comppackk8s-retrievalservice-2018.11.01/oGYwPm8FSgaD7mkpVFORMg]]can not be imported as a dangling index, as index with same name already exists in cluster metadata`	This type of warning message is caused by an incorrect upgrade or re-deploy operation, follow the upgrade and install instructions: Deploying stand-alone Elasticsearch.
