npm:undici not working (Connect Timeout Error)

[KohnoseLami]

It appears to have been resolved as a result of the following issue, but it still does not work in my environment.
#16710

I used @discordjs/rest to test the behavior, but only undici actually causes errors.

import { request } from "npm:undici"
await request("https://jsonplaceholder.typicode.com/todos/1")

My enviroments:
deno 1.34.3 (release, x86_64-pc-windows-msvc)
v8 11.5.150.2
typescript 5.0.4

I am not able to reproduce this; possibly a windows specific error?

[KohnoseLami]

Maybe yes
I prepared another Windows machine for the experiment and did it from installation, but I get a similar error.
I ran it on Windows 11 and Windows 10 and it was similar.

Of course fetch works in environments where undici doesn't work. So it's not about the network or anything.

+1.

I try to use it in WSL and all works fine.
But if I switch to Windows I get the same error...

It is lock to use my framework on Windows in Deno runtime...

[kravetsone]

import { request } from "npm:undici";

console.log(await request("https://jsonplaceholder.typicode.com/todos/1"));

Seems like it works now on Deno 2.0
