Fess13.5をwindows環境にインストールを行いました。
手順書に沿って環境構築を行い、管理者管理のページまでアクセスすることができました。
その後、DBより取得する必要があるので、こちらの手順に沿ってプラグインのインストールを実施しようとしています。
しかし、プラグインのタブの中のインストールボタンを押した時点で、システムエラーページに遷移してしまいます。
Fessのインストール後に行った作業としては、adminユーザーのパスワードの変更のみであるので、特殊な操作を行ったとは考えにくいです。
対応方法や調査方法について、ご教示いただけますでしょうか。
（ちなみに、Fessを利用している環境はネットワークに繋がっていないので、ローカルよりファイルをアップロードして使用すると考えていました。）
（追記）
バージョンを12.5に下げることで、プラグインの機能自体がなくなったので、暫定的にダウングレードすることで回避しています。
fess.logに例外が出力されていないかを確認してください。
横から失礼いたします。
私も同じ事象が発生しています。
fess.logには、Connection timed out が出力されています。

環境は以下の通りです。
OS：Windows10（1909）
fess：13.6.0
Elasticsearch：7.6.0
また、関連があるかは不明ですが、データストアのクロール画面の「ハンドラ名」で何も出てきません。
同様の事象の方はいらっしゃいませんか？
プロキシを介さずにインターネットにアクセスできるようサーバの設定を変更したところ、プラグインのインストールと、データストアのクロール画面が正常に動くようになりました。
当方、プロキシが必須の環境なのですが、プロキシの設定はどこで行えばいいのでしょうか？
ご教授いただければ幸いです。
fess_config.propertiesのhttp.proxy.*あたりの設定を試してみてください。
ご回答ありがとうございます。
fess_config.propertiesのhttp.proxy.*に、プロキシサーバのサーバ名とポート番号（4-5行目）を設定してみましたが、結果は変わりませんでした。
virtual.host.headers=
http.proxy.host=proxy.hoge.co.jp
http.proxy.port=8080
http.proxy.username=
http.proxy.password=
http.fileupload.max.size=262144000
http.fileupload.threshold.size=262144
プロキシが効かないようなので、次のリリースで設定できるようにします。
ありがとうございます。
次のリリースを楽しみにしています。
13.6.1でプラグインのインストールができるようになりました。
また、データストアのクロール画面の「ハンドラ名」にも選択肢が表示・選択できるようになりました。
ご対応、ありがとうございました。
