HMR in docker not working when using reverse proxy

When using the docker and caddy revers proxy the hmr is not working , but if I don't use reverseproxy only docker it works fine. chrome error in console 
client:535 Mixed Content: The page at 'https://nuxtnew.larabells.local/' was loaded over HTTPS, but attempted to connect to the insecure WebSocket endpoint 'ws://nuxtnew.larabells.local:443/_nuxt/'. This request has been blocked; this endpoint must be available over WSS.

here is my caddfile 
nuxtnew.larabells.local {

    @websockets {
            header Connection *Upgrade*
            header Upgrade websocket
    }
     reverse_proxy @websockets nuxtnew_container:24678
     reverse_proxy nuxtnew_container:4000
}
nuxtnew.larabells.local {

    @websockets {
            header Connection *Upgrade*
            header Upgrade websocket
    }
     reverse_proxy @websockets nuxtnew_container:24678
     reverse_proxy nuxtnew_container:4000
}
here is the nuxtconfig 
// https://nuxt.com/docs/api/configuration/nuxt-config
export default defineNuxtConfig({
  compatibilityDate: '2024-04-03',
  devtools: { enabled: false },

  devServer: {
    port: 4000,
    host: '0.0.0.0',
  },
  vite: {
    server: {
      hmr: {
        protocol: 'wss',
        clientPort: 443,
      },
    },
  },
  modules: ["@nuxtjs/tailwindcss", "shadcn-nuxt"],
  shadcn: {
    /**
     * Prefix for all the imported component
     */
    prefix: '',
    /**
     * Directory that the component lives in.
     * @default "./components/ui"
     */
    componentDir: './components/ui'
  }
})

Reverse proxying is really a pull-your-hair-and-bang-the-wall thing within docker 😦 We've currently got it working with this setup (reverse proxy is Apache -- we are stuck to that): 
// (part of) nuxt.config.js
vite: {
    server: {
      hmr: {
        path: 'ws',

  },

vite: {
    server: {
      hmr: {

      }
    },

Maybe this will be of use for you. As it's a long time ago we got this working, I don't remember all the details on how/why this works.
