我使用以下脚本创建自签名证书，但是，当我尝试验证SSL证书时，会出现以下错误消息。

证书由以下命令创建：C：\Certs

    C:\Certs>openssl s_client -connect serv.org.com:3002 --quiet -CAfile C:\Certs\ca.crt
    depth=1 O = Proton, CN = Proton Certificate Authority
    verify error:num=19:self-signed certificate in certificate chain
    verify return:1
    depth=1 O = Proton, CN = Proton Certificate Authority
    verify return:1
    depth=0 O = Proton, CN = 192.168.176.130
    verify return:1
