tauri: WSL Unable to init server

yarn tauri dev fails when trying to start.

To Reproduce

1. Follow steps for Linux setup and install Tauri node package globally
2. Also enable Windows loopback (I did this just in case because I’m on WSL 2)
3. Create a new project (I’m using Svelte) and add node package locally
4. Edit tauri.conf.json

  "build": {
    "distDir": "../public",
    "devPath": "http://127.0.0.1:5000"
  },

1. Run yarn dev to start up Svelte dev server
2. Run yarn tauri dev in a different terminal tab

Expected behavior I expect the Tauri dev environment to start up.

Platform and Versions:

OS: Linux(4.19.84-microsoft-standard) - linux/x64 Node: 13.6.0 NPM: 6.13.4 Yarn: 1.21.1 Rustc: 1.42.0-nightly

Additional context Note that this is my first time trying out Tauri, but as a JS/Rust user I’m very excited!
