如何解决错误后禁用Jenkins代理：java.io.IOException：后备通道'来自ip-'XXX'的JNLP4-connect连接已断开
我们使用jenkins CI在Mac-Mini（macOS Catalina v.10.15）上运行Appium（iOS和Android）测试
由于控制台输出中的错误，jenkins代理已禁用时间（每天几次）：
[Allure] [XXXXXXX Job run [https://XXXXX/jobrun/XXXXX] stopped successfully...
15:19:58 ERROR: Failed to parse POMs

在Mac-mini上安装并在jenkins代理中指定的Java版本是相同的。
机器的硬盘驱动器中有很多可用内存空间，并且Teamcity代理未检测到此类问题。网络连接稳定（希望如此）。
重新启动jenkins代理可以帮助几个小时，但是会再次发生错误。 有人可以帮忙解决此问题吗？
