Firewall settings prevent connecting to WSL

[costas90]

• VSCode Version: 1.37.1
• Local OS Version: Windows 10, version 1903
• Remote OS Version:
• Remote Extension/Connection Type: WSL

This problem appeared today after updating Windows to version 1903. Also, when I disable the firewall from Avast Antivirus it works!

But I dont know how to fix the issue because I want the firewall enabled at all times..

In the firewall logs, it seems that svchost.exe is related, but checking the application rules, all connections are allowed.

What am I missing?

Steps to Reproduce:

1. Run 'code .' in Ubuntu Bash
2. New VS Code window opens but gives the error "Failed to connect to the remote extension host server (Error: connect ETIMEDOUT 127.0.0.1:51072)"

I tried rolling back VS Code to 1.36.1 and I get similar errors.

Similar errors and it says it cannot connect to the extensions marketplace..

In another thread people talk about removing the () from the hostname, but I am not sure where to locate this. Or is that not relevant to WSL?

I tried running this from the Insiders V. 1.38

In stable VS Code I cant get the log, but in Insiders I can,, here it is:

The server seems to be running as the log shows

When you open a browser on http://127.0.0.1:50902/version, does that work?
Can you also try the other IPs listed and http://localhost:50902/version?

I ended up rolling back the Windows version from 1903 to 1803 and now it works.

I did try visiting those URLs but did not work.

I have the same issue but I am unable to roll back to a previous Windows version. Any solutions?

Following #927 (comment), I noticed that it was indeed my antivirus software as well (AVG, for those wondering)

@mikeweltevrede you can roll back windows if no more than 10 days have past since the upgrade.

@mikeweltevrede did you manage to make this work with your antivirus?

My windows were auto-updated and I have this problem again..

[mikeweltevrede]

@costas90 it is working only if I turn off my virus control before starting VS Code, unfortunately

Anyone find a way around this that does not involve shutting down antivirus firewall?
