Systems without IPv6 support crash netlify dev

[cfjedimaster]

Describe the bug

For a very long time, I used the following to start my Eleventy site:

netlify dev -c "eleventy --serve --quiet"

A week or so ago, it began throwing an error:

 Starting Netlify Dev with Eleventy
✖ Waiting for framework port 8080. This can be configured using the 'targetPort' property in the netlify.toml
◈ Netlify Dev could not connect to localhost:8080.
◈ Please make sure your framework server is running on port 8080

What's interesting is that the error would throw right away. It didn't wait for Eleventy to start. I confirmed localhost worked via ping, and I could still run eleventy in my directory just fine.

You can see my forum post here: https://answers.netlify.com/t/ntl-dev-no-longer-working-with-eleventy/76968

This morning, I noticed how it said "with Eleventy", and I realized the CLI recognized Eleventy and was maybe assuming it was running already? On a whim, I tried this in my toml:

[dev]
  framework = "#static"

And voila, it worked. It correctly ran the command to start Eleventy.

So my question is - what changed here?

Steps to reproduce

With an Eleventy site, try running it as described above (with -c), and see if the CLI doesn't launch Eleventy.

Configuration

No response

Environment

  System:
    OS: Linux 5.15 Ubuntu 22.04.1 LTS 22.04.1 LTS (Jammy Jellyfish)
    CPU: (20) x64 Intel(R) Core(TM) i9-10900K CPU @ 3.70GHz
    Memory: 9.28 GB / 15.46 GB
    Container: Yes
    Shell: 5.1.16 - /bin/bash
  Binaries:
    Node: 14.18.0 - ~/.nvm/versions/node/v14.18.0/bin/node
    npm: 7.24.1 - ~/.nvm/versions/node/v14.18.0/bin/npm
  npmGlobalPackages:
    netlify-cli: 12.0.9

A temporary fix for this is

[dev]
  targetPort = "8080

I had a similar issue with SvelteKit when it switched to Vite's 5173 port. The framework info needed to be updated in the json file.

[cfjedimaster]

Adding targetPort didn't work for me.

[brittneypostma]

Oh, that's odd. I think what happened and why it started working when you changed to static is that it stopped detecting the framework with eleventy.json. I'm not familiar with Eleventy, do you notice anything wrong with the json file?

[cfjedimaster]

Well that's the thing - it did detect Eleventy. I saw that in the output, but it didn't fire it up like it used to.

[danez]

Can you please test with version 12.0.10? This new version should show the underlying error in this case, because if it instantly throws that means something went wrong before it even started to wait for the port.

[cfjedimaster]

Big paste coming in.

I really think the 'localhost cant be found thing' is a misfire, and this is the important bit:

Please make sure your framework server is running on port 8080

Previously, the CLI would use my -c to fire up Eleventy.

I was able to reproduce this on Ubuntu with IPv6 completely disabled. I will start creating a fix for this.

Can you confirm that IPv6 is disabled on your machine? For example doing nslookup localhost should only print 127.0.0.1 but not ::1.

[danez]

This should be solved with 12.0.11.

If the problem persists please reopen.

I used the techniques here, https://www.golinuxcloud.com/linux-check-ipv6-enabled/, and from what I can tell, IPv6 is not disabled, but, I updated, and everything works now, so the problem is fixed. :) Thank you.

Oh, as an aside, nslookup localhost returned something weird:

Server:         1.1.1.1
Address:        1.1.1.1#53

** server can't find localhost: NXDOMAIN

Should I be concerned?
