连接被对方​​拒绝：111：连接被拒绝

Question

我有一个用于 LinkedIn 的蜘蛛。它在我的本地机器上运行良好，但是当我在 Scrapinghub 上部署时出现错误：

Error downloading <GET https://www.linkedin.com/>: Connection was refused by other side: 111: Connection refused.

领英prohibits scraping:

禁止的软件和扩展程序

LinkedIn 致力于保护其会员数据的安全，并确保其网站免遭欺诈和滥用。为了保护我们的会员数据和我们的网站，我们不允许使用任何第三方软件，包括“爬虫”、机器人、浏览器插件或浏览器扩展（也称为“附加组件”），抓取、修改外观或自动执行 LinkedIn 网站上的活动。此类工具违反了User Agreement，包括但不限于第 8.2 节中列出的许多“注意事项”……

有理由认为他们可能会主动阻止来自 Scrapinghub 和类似服务的连接。
