External URL request does not work

[bptsd]

Hello - I'm new to hono and I'm wondering if someone can explain why requests to external hosts/URL is not working for me. Everything external returns "NOT FOUND". If i simply switch to a local route /local/test (local URL) it works fine and returns HTTP OK.

Here is the code:

import { Hono } from 'hono'
import { logger } from 'hono/logger'
import { cors } from 'hono/cors'

const app = new Hono()
const externalURL = "http://google.com"; 
const internalURL = "/local/test"


app.use('*', logger())
app.use('/external/*', cors())
app.get('/external', async(c) => {
    

/* CHANGING THIS CAUSES ANY EXTERNAL URL TO RETURN NOT FOUND */
    //const res = await app.request(internalURL)
    const res = await app.request(externalURL)



  
    return c.text(`RESPONSE: ${res.statusText}`)
  })

  app.get('/local/test', (c) => {
    return c.text('hello world')
  })

  

export default app
