Ubuntu 20.04です。  
`sudo apt install
nginx`してインストール後、curlでサーバーのIPに接続したところ、Nginxのウェルカムページのhtmlがかえってきました。  
しかしブラウザで同じIPに接続するとタイムアウトします。  
Nginxのログには何も書かれていません。

設定ファイルはデフォルトのままいじっていません。

解決策はありますか？

question
ubuntu nginx
Nginxでcurlでは正常に接続できるがブラウザからはタイムアウトする
さくらVPSのパケットフィルタ機能が原因でした。  
管理ページからTCP 80/443を開放することで解決しました。
