[Bug]: Socket connection to 'wss://domain.com/ng-cli-ws' failed: in chrome's developer console when running angular in code-server

从 code-server 代理指南开始，通过 EKS 和 Emissary-ingress 重现部署，然后检查 src/index.html 中的 base href 和 package.json 中的 ng serve 设置。使用 Chrome 的开发者控制台，将失败的 WebSocket 路径与已配置的映射进行比较；当 Angular 应用在没有 ng-cli-ws 连接错误的情况下加载时，即表示完成。

Is there an existing issue for this?

OS/Web Information

• Web Browser: Chrome
• Local OS: Ubuntu
• Remote OS: Ubuntu
• Remote Architecture: amd64
• code-server --version: 4.12.0

Steps to Reproduce

1. Deploy code-server as pod and create service in EKS cluster
2. Use Emissary-ingress as proxy and create mapping to code-server userpod (eg /tempmap/ --> userpod service)
3. Access the userpod at the URL www.domain.tld/tempmap/
4. Install Nvm , npm and angular
5. switch to the created directory and do ng serve and access the browser
6. Now we will get white screen error
7. Follow the code-server proxy guidelines
8. try a) use in src/index.html
   b) add --serve-path /absproxy/4200 to ng serve in your package.json
9. Socket connection to 'wss://domain.tld/ng-cli-ws' failed: not found error in chrome's developer console

Expected

Not getting Socket connection to 'wss://domain.tld/ng-cli-ws' failed: error in chrome developer consoleWebSocket

Actual

Getting webSocket connection to 'wss://domain.tld/ng-cli-ws' failed error

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

Code-server is deployed on AWS EKS cluster, and I am using emissary-ingress as proxy to access code-server. SSL is attached to AWS application load balancer used to access code-server. We are getting this error not always but getting them randomly.
