【rails6】 webpack-dev-serverを起動するとCSSが効かなくなる

Question

webpackerでcssを読み込ませて、
webpack-dev-serverでホットリロードして開発したいのですが、
起動すると（Compiled successfullyは表示されず下記になります。）cssが効かない状態になってしまいます。
再度、bin/webpackでコンパイルすれば元に戻る状態です。

rails/webpacker/#2688
こちらを確認して、bundle exec rails webpacker:compileを行ったら、すでにアップデートされており、
webpacker.ymlのcompile: trueになっており、
改善策が見つからずでございます。

ご教授をお願いできませんでしょうか。
よろしくお願いいたします。

追記
dev-server起動時に表示されるhttp://localhost:8080/にアクセスしてみたら、
以前、nuxtjsの練習で開発していた時の様な画面が表示されました。

接続先を3035にして、rails側でどうにかしたいです。

ご教授お願いできませんでしょうか。
よろしくお願いします。

Everything's up-to-date. Nothing to do

railsサーバーには下記のエラーが表示されてます。

ActionController::RoutingError (No route matches [GET] "/packs/js/application-d92e6843ff26022b8d77.js")

consoleには同じ様なエラーが表示されております。

http://localhost:4000/packs/js/application-d92e6843ff26022b8d77.js net::ERR_ABORTED 404 (Not Found)
