LINE botが動かない

Question

前提・実現したいこと

nginx・uWSGI・line-bot-sdkなどを用いて自宅サーバーからbotを公開したい

※以降ドメイン名mydomain.jpを使用しているものとします

発生している問題・エラーメッセージ

・自分のドメインを打ち込んでアクセスすると

400 Bad Request The plain HTTP request was sent to HTTPS port 

と表示される
・systemctlによるとnginx/uwsgiともにactive(running)となるがnginxは以下の警告が出る

Sep 29 00:16:11 ubuntu nginx[4383]: nginx: [warn] the "ssl" directive is deprecated, use the "listen ... ssl" directive instead in /etc/nginx/conf.d/linebot.conf:5
Sep 29 00:16:11 ubuntu nginx[4383]: nginx: [warn] conflicting server name "mydomain.jp" on 0.0.0.0:443, ignored
Sep 29 00:16:11 ubuntu nginx[4384]: nginx: [warn] the "ssl" directive is deprecated, use the "listen ... ssl" directive instead in /etc/nginx/conf.d/linebot.conf:5
Sep 29 00:16:11 ubuntu nginx[4384]: nginx: [warn] conflicting server name "mydomain.jp" on 0.0.0.0:443, ignored

・また、当然line bot は既読無視してきます

・なお、Heroku ngrok等環境では動作したのでmain.pyはあっている可能性が高いです

こちらを参考にしましたが余り意味はわかってないです

ポート転送の設定は完了済みで、Hello nginx!も問題なくhttpsプロトコルで見ることが出来ました。設定ファイルをいじるまでは...

lineではhttps://mydomain.jp:443/callbackをウェブフックとして使用
