use an example from the repo to do the same.

import { request } from 'undici'
(async () => {const {
  statusCode,
  headers,
  trailers,
  body
} = await request('http://192.168.20.12:11434/api/tags')
console.log('response received', statusCode)
console.log('headers', headers)
for await (const data of body) { console.log('data', data) }
console.log('trailers', trailers)})()

and see error

Additional context

[metcoder95]

The EHOSTUNREACH mostly relates to routing issues in your OS host tables, although it puzzles me that it worked for curl.

Does traceroute shows something extraneous?

[varris]

nothing extra in traceroute

$ traceroute 192.168.20.12
