@vue/cli 4.5.15 " [WDS] Disconnected! "

[patialo]

I use the domain name to access code-server and install the initialized project through vuecli
after "npm run serve"

Use ip:8080 to access the running of this project, but the console keeps prompting "[WDS] Disconnected!"

This is just an initialization project without any configuration
I tried many ways to fix it, but none worked(such as : configure vue.config.js-devserver-{host: 127.0.0.1}or{0.0.0.0} )
(When copying the whole project to my computer (including node_modules), after "npm install" on my vscode ,it doesn't produce this error, there are several packages changed)

what should I check to fix this please？

Take a look at our docs here for proxying a Vue app. That might help.

I tried it but doesn't work for me

as what in the document， i tried these way to access but not work too:
https://<my-domain-name>/absproxy/3454
http://<IP>:8080/absproxy/3454

In addition,when I copy the program that works fine on vscode to the code-server, I get an error when I use "npm run serve" without "npm inastall"

So why is the dependency installed using npm install on code-server different from vscode?(they have the same npm registry)

That is very strange 🤔 I have no idea to be honest. I've run into issues in the past with Vite with HMR and similar things. I'm not sure what we can do to fix this 🤔

This problem was solved by running code-server in docker
