**What are you trying to accomplish**  
On a new vue3 install I was trying to connect [builder.io](http://builder.io) but the preview function is not working on the localhost. I’ve tried doing it over https and changing the chrome settings to allow insecure content, but even then the preview is not loading.

**Screenshots or video link**

**Code stack you are integrating Builder with**  
Vue3

Hello @jaylt,

Welcome to the [builder.io](http://builder.io) forum.

Few things to consider when you are experiencing a preview error

1. Make sure the local server is running and you are using the correct preview URL [http://127.0.0.1:5173/](http://127.0.0.1:5173/) or [http://127.0.0.1:3000/](http://127.0.0.1:5173/)
2. Builder API key, your builder space API key is 711d6471bccf41d59b3ed99cf66fcea5
3. Check if you are getting any console errors
