主动连接方提示：

info  2019-09-03T07:20:45.197 thread-0  net_plugin.cpp:2293           handle_message       ] received a go away message from 17.1.0.9:7860, reason = authentication failure

被连接方提示：

error 2019-09-04T09:30:24.112 thread-0  net_plugin.cpp:2715           authenticate_peer    ] Peer web0_92:6886 - 5a05387 sent a handshake with a timestamp skewed by more than 1 second.
error 2019-09-04T09:30:24.112 thread-0  net_plugin.cpp:2251           handle_message       ] Peer not authenticated.  Closing connection.

由于BP节点config设置了对等网络验证

allowed-connection = producers
allowed-connection = specified

此时被链接方已经添加了主动连接方的peer-key

peer-key = "FSC71Uiuk23RACZ2PKDZQUeAgyA4w8g9DYurjtBktNes382zn1tMP"

跟下代码
https://github.com/EOSIO/eos/blob/be804bf63c5092a123c3e1a468559a8164bcd3be/plugins/net_plugin/net_plugin.cpp#L2788

namespace sc = std::chrono;
      sc::system_clock::duration msg_time(msg.time);
      auto time = sc::system_clock::now().time_since_epoch();
      if(time - msg_time > peer_authentication_interval) {
         fc_elog( logger, "Peer ${peer} sent a handshake with a timestamp skewed by more than ${time}.",
                  ("peer", msg.p2p_address)("time", "1 second")); // TODO Add to_variant for std::chrono::system_clock::duration
         return false;
      }

Peer clock may be no more than 1 second skewed from our clock, including network latency.
对等时钟与我们的时钟相差不超过1秒，包括网络延迟。

主动连接方发起连接时（当前机器本地时间）到被连接方处理时（被连方本地时间）不能超过1秒（peer_authentication_interval）
如果超时就直接拒绝

解决方案

各节点开启定时同步时间服务

sudo apt-get install chrony
