リモートUbuntuサーバーにFlask/Neo4jアプリケーションをインストールしようとしていますが、私が把握できなかった問題が発生しました。私のアプリはpy2neoを使っていますが、グラフに接続しようとするとアプリがクラッシュし、Neo4jのプロセスが停止しているようです。私は...このようなPythonシェルで接続失敗しpy2neo SocketError：接続は拒否されましたが、カールが効きます
test = Graph('http://localhost:7474/db/data/',username='neo4j',password='myPassword')
を試みたが、私はそれを再起動するまでものNeo4j動作不能にレンダリングしてきました。しかし、これらは200応答を返す（およびWebインターフェイスも動作します）：
curl -u neo4j http://localhost:7474/db/data/
requests.get('http://localhost:7474/db/data/', auth=('neo4j','myPassword'))
接続がどこでもしかしpy2neoから作品のように、それはそうなので、私は、this similar questionよりも多くの情報を提供しようとしました。私がいただければ幸いで何が起こっているかを把握しようとする可能性があり
