Does this issue happen in VS Code or GitHub Codespaces?

• I cannot reproduce this in VS Code.
• I cannot reproduce this in GitHub Codespaces.

Are you accessing code-server over HTTPS?

• I am using HTTPS.

Notes

There was issue at microsoft/vscode#151438, which was fixed by microsoft/vscode#151500

Looks like code-server wasn't updated to latest VSCode yet.

Awesome! Since this is fixed upstream and we're going to upgrade, I'm going to close this.

[iamfaith]

same here. I have upgraded to the latest version, 4.7.1 77bbed4 with Code 1.71.2. Problem remained.

@iamfaith oh no! Thanks for letting us know. Are you able to reproduce it in vscode.dev or Codespaces?

Could you please tell me how to use IPV6 in vscode.dev?

[iamfaith]

It could be easily reproduced in code-server as follows. It seems to have duplicate brackets.

The workbench failed to connect to the server (Error: Failed to construct 'WebSocket': The URL 'ws://[[2409:8a55:223b:7380:xxxxxxxxxxxxx]]:8080/stable-74b1f979648cc44d385a2286793c226e611f59e7?reconnectionToken=58166be8-c072-4962-bfb5-dbb1d5edb8f7&reconnection=false&skipWebSocketFrames=false' is invalid.)

Hmm...I don't really know to be honest. @code-asher do you know if it's possible?

Edit: see #5675
