仅当在Jenkins上执行测试时，获取未知主机异常错误

我有一个基于selenium的测试，它涉及API验证。该步骤生成oAuth令牌，然后继续命中所需的端点

我面临的问题是oAuth令牌生成只有在Jenkins上运行的测试出现未知主机异常时才会失败

出于调试目的，我尝试在本地执行上复制相同的行为，但它可以无缝地工作。我还通过postman手动检查了端点、授权和验证了令牌生成，并且成功了

我很难理解问题到底出在哪里。我试图探索这是否是由于Jenkins的一些配置设置失控造成的，但到目前为止我还无法得出结论。 如果有人经历过这一点并能指导我找到解决方案，我将不胜感激。如果有任何现有的答案/文档涉及到这一点，请告诉我

这是执行错误日志：

该错误意味着计算机无法解析主机名的IP地址。您是否使用ssh连接到它以尝试使用

nslookup

解决它？如果您处于典型的公司设置中，则需要一个代理来发出外部请求（如果允许的话）。
