Hi , We moved to NR 3.0.2 from (v2.2.2). And NodeJS was also upgraded to v18.17.

As a result we see now http request node has stopped working with URLs which have localhost as the server of the URL.

It continues to work where we have server name / IP defined.

Was any change done in NR or NodeJs causing http-request node to stop recognizing localhost ?

I think nodejs 18 prioritises ip6 over ip4 so make sure you have localhost defined in your /etc/hosts file. eg like

```auto
127.0.0.1	localhost
::1 localhost

```
