Which parameter we need to use for network_host in IPv6 for ElasticSearch

Sorry, I don't recognise that exception. Binding to an IPv6 address works for fine me. I'm using Elasticsearch 7.4.0 running on Oracle Corporation/OpenJDK 64-Bit Server VM/12/12+33 on this Linux:

Linux worker-772973 4.15.0-47-generic #50~16.04.1-Ubuntu SMP Fri Mar 15 16:06:21 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux

Maybe you need to upgrade something? If not, hopefully someone else can help since I have no other ideas.
