{frontMatter.description}

<div id="i-am-unable-to-access-a-clickhouse-cloud-service">
  ## 我无法访问 ClickHouse Cloud 服务
</div>

如果您看到如下错误消息，可能是您的 IP Access List 阻止了访问：

```response theme={null}
curl: (35) error:02FFF036:system library:func(4095):Connection reset by peer
```

或

```response theme={null}
curl: (35) LibreSSL SSL_connect: SSL_ERROR_SYSCALL in connection to HOSTNAME.clickhouse.cloud:8443
```

或

```response theme={null}
Code: 210. DB::NetException: SSL connection unexpectedly closed (e46453teek.us-east-2.aws.clickhouse-staging.com:9440). (NETWORK_ERROR)
```

请检查 [IP Access List](/docs/zh/products/cloud/guides/security/connectivity/setting-ip-filters)；如果您是从允许列表之外的地址发起连接，连接将会失败。
