从远程主机复制到远程主机时 Ansible 挂起

Question

我想将 hostA 上生成的文件复制到生产服务器，并尝试了下面的任务，但 Ansible 挂起了。我ssh_args=-i ForwardAgent=yes按照建议进行设置上一篇但这没有效果。这里的问题是什么？

- name: Copy certificate from hostA to production servers                     
  synchronize:                                                   
    mode: pull                                             
    src: /etc/td-agent/ca_cert.pem
    dest: /etc/td-agent/ca_cert.pem                               
  delegate_to: "{{item}}"
  with_items: groups.production

更新：日志如下：
