我使用 KafkIO UI (https://www.kafkio.com) 连接到 Confluence Cloud Schema Registry 时遇到错误。当我点击“测试架构注册表”时，屏幕截图中不断出现超时错误。对于我们尝试过的其他云提供商来说，它通常工作正常。

我尝试使用正确的 apikey 和密码，我知道架构注册表存在并且可以访问，因为我看到同事访问没有问题。有什么想法吗？
看起来您使用的是代理 URL，而不是架构注册表的 URL。这是根据您指定 9092 作为端口这一事实进行的猜测，但这通常用于代理。
您可以在 Confluence Cloud 上的 Stream Governance API 部分获取架构注册表 URL 和基本身份验证密钥/秘密。请参见屏幕截图（未指定端口，因此默认为 443）。希望这就是您的全部问题......
