Not working on IPv6 host #2151
Description
Description
On an IPv6-only host, infrastructure agent is unable to communicate with Newrelic, even if in https://docs.newrelic.com/docs/new-relic-solutions/get-started/networks/ it's reported
These endpoints support both IPv4 and IPv6, and have HTTP/2 and HTTP/3 enabled
Expected Behavior
Newrelic agent to work - it should be enough to be able to define the used endpoint in the agent? cannot find how!
Troubleshooting or NR Diag results
