SQLAlchemy connection via proxy : <p>I need to connect to existing database from SQLAlchemy via proxy. </p>

<pre><code>        self.DB = {
            'drivername': 'oracle',
            'host': url,
            'port': port,
            'username': username,
            'password': password,
            'database': dbname
        }
        _engine = create_engine(URL(**self.DB))

        self.connection = _engine.connect()
</code></pre>

<p>I'm getting:</p>

<pre><code>cx_Oracle.DatabaseError: ORA-12170: TNS:Connect timeout occurred
</code></pre>

<p>And I'm pretty sure I just need proxy because of my company policy. I couldn't find any tips in documentation how can I create connection via proxy.</p>

<p>Any help would be greatly appreciated!</p>
