配置自己的域名时无法使用

[reinershir]

安装一切正常，反复检查了连接信息也是对的，v2ray报如下信息：

[Warning] [2286708102] app/proxyman/outbound: failed to process outbound traffic > proxy/trojan: failed to find an available destination > common/retry: [dial tcp 43.156.135.20:443: i/o timeout dial tcp {ip}:443: operation was canceled dial tcp: lookup domain.com: operation was canceled] > common/retry: all retry attempts failed

如何排查问题？
