 The development server is accessed on a different port from the microscope API. When Vite starts, it creates a proxy that proxies all routes starting with `/api` to `http://localhost:5000/api`. This is useful when using either the simulation server or when developing directly on a microscope.

 If your microscope hostname is not `microscope`, you can use local environment files to override this route. Create the file `.env.local` within the `/webapp/` directory, and in that file add the line
 
-    VITE_MICROSCPOPE_HOST=http://myhostname.local:5000
+    VITE_MICROSCOPE_HOST=http://myhostname.local:5000
