1. Fixed the issue of network disconnection and node inability to connect caused by DNS.
2. Changed the delay check mode timeout to 15 seconds (in network environments that do not support IPv6, if Karing's IPv6 switch is enabled, it is recommended to set this value to >10 seconds, otherwise the delay check may time out).

1. 修复由dns导致的断流,节点无法连接的问题
2. 延迟检查模式时间改为15s(在不支持ipv6的网络环境,启用karing的ipv6开关的情况下,建议将此值设置到>10s,否则延迟检查容易超时)
