问题 处理命令时发生未知的服务器端错误。原始错误：300秒后未收到任何响应
环境 出现此问题的Appium版本（或git版本）：1.15.0 / 1.15.1 用于运行Appium的桌面操作系统/版本：mac OS 10.15.1 Node.js版本（除非使用Appium.app | exe）：v13.2.0 Npm或Yarn包管理器：6.13.1 测试中的移动平台/版本：iOS 13.1.2 真实设备或模拟器/模拟器：iPhone X
详细信息 我在iOS 13.1.2上运行网络测试。前面的步骤可以正确执行。同时执行CLICK命令。花了大约10分钟的时间，并报告了上面的错误。
我曾经使用Appium 1.15.1，现在降级到1.15.0。我还尝试了升级和降级Katalon Studio版本，但问题仍然存在。
