我正在尝试在我的Linux服务器(Debian GNU/Linux 10 buster(和位于另一台服务器中的微服务之间建立通信。Telnet运行良好，但当我尝试执行curl时，我会收到以下错误：
$ curl "https://url.com.br/path"
curl:(60(SSL证书问题：无法获取本地颁发者证书此处提供更多详细信息：https://curl.haxx.se/docs/sslcerts.html
curl无法验证服务器的合法性，因此可能未与其建立安全连接。若要了解有关此的详细信息情况和如何解决，请访问上述网页在上面
我也有2.cer，但我不确定我应该做什么
编辑：
尝试按照@cashif的建议使用-kv执行，输出如下：
