WSL2: connection issues on localhost #2037

Kangaroux · 2019-12-15T19:14:41Z

VSCode Version: 1.41.0
OS Version: 19041.1

Does this issue occur when all extensions are disabled?: Yes

After upgrading my windows insider build last night vscode is giving ECONNREFUSED errors.

I'm unable to manage any of my extensions. Under the recommended extensions tab it says "We cannot connect to the Extensions Marketplace at this time, please try again later."

Additionally, the Terminal window is stuck on "Starting...". I can't open any projects in WSL, and opening projects as non-WSL still gives extension errors. Opening a WSL project gives "Could not fetch remote environment."

I'm not able to reproduce on Windows 19041.1 (Build 19041.vb_release.191206-1406)

Can you paste what's in the WSL Log (Use Remote-WSL: Show Log)?

If I open a project without WSL the bash terminal works as expected. I checked the permissions for the .vscode_server folder and everything seems to be fine.

aeschli · 2019-12-17T08:15:38Z

Thanks @Kangaroux
Can you close all VSCode windows, and check with ps -ax in the WSL terminal that there's are no more VSCode server processes running (kill the processes, if necessary).

Then open a WSL window again and copy the WSL log.

What do you mean by project without WSL?
Screenshots would be helpful to understand the issue you're seeing.

Kangaroux · 2019-12-17T11:47:54Z

When I say a project without using WSL I mean using this:

I have the exact same issue. But i'm not sure the issue is related to the Windows update for me. It has happened now and then for a while. A reboot solves the issue.

OS Version: 19041.1
VSCode Version: 1.41.0

Running Ubuntu-18.04 WSL 2

Kangaroux · 2019-12-17T17:25:08Z

Can confirm a reboot fixed it for me as well.

phenixdotnet · 2019-12-18T15:44:56Z

Hi,
Same issue, appearing just after updated to Windows 10 Insider 19536.
I got it in both stable and insider version of VS code.

A curl from powershell fail:

> curl "http://[::1]:42437/version"
curl: (7) Failed to connect to ::1 port 42437: Connection refused

But a curl from ubuntu is ok:

> curl "http://[::1]:42437/version"

kobenauf · 2019-12-19T18:22:13Z

I have this problem too, and I wonder if it is related to #103

I am also trying to track down an issue where sometimes when I start a node program in bash (wsl 2), localhost is accessible from my browser in Windows, and sometimes it's not.

It seems like if I reboot, if I first start my program, I am able to connect to localhost from my browser, but then running code . from bash leads to VSC having the connection errors reported in this issue.

However, if I reboot and first run code ., VSC loads correctly, but then my browser is unable to connect to my program on localhost.

Here are other possibly related issues:
microsoft/WSL#2471
microsoft/WSL#4353

Kangaroux · 2019-12-19T19:14:13Z

Node has been a bit flaky for me as well, whether I'm running it directly or through Docker. Most of the time it's fine, though sometimes I can only access it via curl and not through my browser. I haven't found any pattern with it happening.

Exactly what is happening to me, what I open first, runs, after that, I only get connection refused.

dsod · 2019-12-28T14:54:33Z

It's probably related to:
microsoft/WSL#4340
and
microsoft/WSL#4769

The 'only one port works' makes sense as all of us manage to get it working after a reboot and if we start vscode first after reboot.

Is it possible for the VSCode server to use IP instead of localhost? Looks like we could use that as a work around for now.

aeschli · 2019-12-30T13:32:53Z

I'll add an option to use the ip address as a workaround.

Zeswen · 2020-01-02T12:38:52Z

+1

zoftdev · 2020-01-04T07:00:05Z

for interim, wsl --shutdown solve my problem.

aeschli · 2020-01-06T09:18:38Z

I just released a new version of the extension - Remote - WSL 0.42.1 - that should work around the issue by connecting to the WSL2 VM IP. It requires VSCode Insiders (1.42.0). It would be great if you can give it a try. If it works I can also make a version for the stable VSCode (1.41.1).

dbaeumer · 2020-01-30T15:01:16Z

Using VS Code with WSL2 verz frequently and have not seen the issue. Marking as verified,

ShadowEO · 2020-02-17T21:56:39Z

VSCode Insiders version of the extension seems to work fine, although I had a connection issue attempting to open a remote folder.
