phpMyAdminでリモートMariaDBサーバーにログインできないが、シェルでは機能する

最近、2台のサーバーを構成しました。 ApacheとphpMyAdminを初めて使用します。もう一方のサーバーには、maria-DBサーバーが正しく構成されています。

phpMyAdminは設定ファイルを読み込んでいますが、MariaDBサーバーに接続できず、PMAがスローしています

#2002 Cannot log in to the MySQL server

phpMyAdmin Error

mysqlコマンドを使用してWebサーバーからデータベースサーバーに接続し、同じユーザー/パスワードを使用して、データベースサーバーに正常に接続できます。

Mysqlでエラーは発生せず、mysqlのすべてのポートがファイアウォールで開かれ、phpエラーは発生しません。私は問題を見つけることができませんでした。
