Hi Brody,

Thanks, I have read the docs page but couldn't work out how this was related to my issue. I never had to define a port for my main app before

Please see the image in the docs, that is the same error page you are getting when you open your domain.

Please follow the docs solution.

Are there any docs to help with using NIXPACKS? I have searched for the last hour and cannot find anything that can help.

I updated the vite config for my laravel app to use port 3000 and host 0.0.0.0 but still getting the same error.

The issue here is that your start command does not start the web server, please remove it.

Ah! That’s it, thank you Brody.
