Steps to reproduce

run 'vue ui' from terminal

What is expected?

Vue UI tool is started and launched automatically on http://localhost:8000

What is actually happening?

Terminal reports:

'🚀  Starting GUI...
🌠  Ready on http://localhost:8000

New tab is launched in Chrome, but nothing is displayed.

---

Recently updated from version 3.3.0. Was having previously noted issue where using Vue UI tool would fail to build new projects correctly with that version. Have attempted npm uninstall/reinstall of vue and @vue/cli with same results.

Additional Note: Receive following warning when running npm install -g @vue/cli:

npm WARN deprecated cross-spawn-async@2.2.5: cross-spawn no longer requires a build toolchain, use it instead

Suggest updating dependency to require cross-spawn in npm config to ensure newer package is used.

Forced to refresh the browser should be fine.

Refreshing the browser does not fix this. Using another browser (Firefox or GNOME web) on my Arch Linux system works fine. If I use the path http://localhost:8000/project/select that also works fine in Chrome. I see these errors in my console https://imgur.com/a/XyJUq9D. Both JS files contain HTML. I am using vue-cli 3.5.4.

I just starting trying out Vue and UI in the last few days. This and another basic issue #3664 are very disappointing :(

@bulletmark The GUI is still in beta, if you want the stable experience use the CLI in the terminal.

There must be a bug somewhere because vue ui is not working after installing everything from scratch node.js (10.16.3 LTS), npm and @vue/cli.

Firefox shows this error:
An error occurred during a connection to localhost:8000. SSL received a record that exceeded the maximum permissible length. Error code: SSL_ERROR_RX_RECORD_TOO_LONG

Chrome shows this error:
ERR_SSL_PROTOCOL_ERROR

Do you have any idea why the SSL of the ui could be broken?

Updated from 10.15.1 to 10.16.3.
Same problem.
Reverted back to 10.15.1 and vue ui worked again
Tried 10.16.3 again and it died
Updated to the latest version 12.11.1 and vue ui works again
So somewhere between 10.15.1 and the latest version it doesn't work (or perhaps just 10.16.3 LTS specifically)

Unfortunately now building the project doesn't work anymore and throws out other errors
