无法使用 postgres 和 sqlalchemy 连接到 aws rds

Question

我使用 Easy create（提供默认和推荐配置）在 aws rds 中创建了一个 db 实例，然后我将 Publicly 可访问设置为 true。 当我尝试使用我的 fastapi 应用程序和代码进行连接时：

from sqlalchemy import create_engine
from sqlalchemy.ext.declarative import declarative_base
from sqlalchemy.orm import sessionmaker

SQLALCHEMY_DATABASE_URL = "postgresql://tayibat:tayibat123!@database-1.cshqjmxxxxx.eu-central-1.rds.amazonaws.com:/database-1"

engine = create_engine(SQLALCHEMY_DATABASE_URL)
SessionLocal = sessionmaker(autocommit=False, autoflush=False, bind=engine)

Base = declarative_base()

它显示在错误中：

    conn = _connect(dsn, connection_factory=connection_factory, **kwasync)
sqlalchemy.exc.OperationalError: (psycopg2.OperationalError) connection to server at "database-1.cshqjmfxxxxx.eu-central-1.rds.amazonaws.com" (3.72.174.85), port 5432 failed: Connection timed out (0x0000274C/10060)
        Is the server running on that host and accepting TCP/IP connections?

db实例的配置是：
