heroku環境でmemcachedのエラー

ローカル環境で開発したwebアプリをherokuにデプロイしたところ、ローカルではできていたログインができなく、herokuのログを見ると以下のエラーが出ていました。

Warning: Warning (512): Cache engine Cake\Cache\Engine\MemcachedEngine is not properly configured. in [/app/vendor/cakephp/cakephp/src/Cache/Cache.php, line 178]

設定がうまくできていないみたいなので、設定ファイルを確認しましたが、どこが違うのか見当がつきません。

herokuのドキュメントを見ていたら、プロトコルの設定？のことが書いてあり、これだと思い実行してみましたが変わりませんでした。

開発環境は以下のお通りです。
centos: 6.10
php: 5.6
cakephp: 3.8

よろしくお願いいたします。
