The guy who manages the most popular template has not fixed an ongoing issue w/ the proxy service. You can just disregard the proxy (and lsp component); it's not vital to using windmill.

Instead, just access the 'server' directly:

1. Open the project in railway
2. select the 'server' component
3. open the Settings tab
4. Find 'Networking' -> 'Public Networking'. I can't remember if railway provides a public URL out of the gate, or you have to create one (or you can add a custom domain). But once you've got a URL, you can just plug that into your browser and use windmill. enjoy
