Data from Elasticsearch cluster with IPv6 addresses offloaded to files

Affected versions

Any version prior to DataMiner 10.2.0 [CU11]/10.3.2 using an Elasticsearch cluster that runs on IPv6 addresses.

Cause

Because IPV6 addresses were parsed incorrectly, DataMiner believed that the Elasticsearch cluster was down. As a result, data was offloaded to files instead of to the database.

Fix

Install DataMiner 10.2.0 [CU11] or 10.3.2.

Issue description
