Web Server not bound to IPv6 address

[thedufer]

nodejs.org is advertising both IPv4 and IPv6 addresses:

> dig nodejs.org AAAA
...
nodejs.org.     235 IN  AAAA    2400:cb00:2048:1::6814:162e
nodejs.org.     235 IN  AAAA    2400:cb00:2048:1::6814:172e

> dig nodejs.org A
...
nodejs.org.     203 IN  A   104.20.23.46
nodejs.org.     203 IN  A   104.20.22.46

However, connections to the IPv6 addresses simply hang until the client times out. This means that remote nvm commands, when curl chooses to try v6, take a minimum of 2 minutes. This is true of the newest nvm (0.29.0).

could you try again please @thedufer, they should be good to go now

I'm seeing the same issue. After a curl, it just hangs trying to connect:

> curl -vvv -6 http://nodejs.org/dist/
* Adding handle: conn: 0x7fbaca804400
* Adding handle: send: 0
* Adding handle: recv: 0
* Curl_addHandleToPipeline: length: 1
* - Conn 0 (0x7fbaca804400) send_pipe: 1, recv_pipe: 0
* About to connect() to nodejs.org port 80 (#0)
*   Trying 2400:cb00:2048:1::6814:162e...

Eventually it just times out.

Both http and https work with the -4 flag and time out with the -6 flag.

Fails directly for me (http and https), -4 works fine:

Works for me

Ah, sorry. Works for me as well, IPv6 was disabled on my local router. 😓

[fhemberger]

@thedufer Can you please check if the problem is fixed for you, so we can close this issue?

[thedufer]

Sorry for the slow response. Yeah, it looks better now. I think my most recent comment was after running while I was on a VPN that doesn't play nicely with IPv6, so that may have been a false negative.
