我已在我的计算机上创建了一个主服务器，其凭据文件在网络上具有公共ip，而不是localhost，如下所示：

./bin/mesos-master.sh --ip=192.168.0.3 --work_dir=/var/lib/mesos --credentials=file://master-cred.json

然后我在另一台机器上创建了一个从机，如下所示：

./bin/mesos-slave.sh --ip=192.168.0.19 --master=<master-ip>:5050 --credential=file://slave-cred.json

然后，主机输出一个传入的身份验证请求，但每次都被拒绝：

I0903 15:17:48.264104 165863424 master.cpp:4728] Authenticating slave(1)@192.168.0.19:5051

两个凭证文件都正确。
这是从机的输出：

但是，当我从与主服务器相同的机器上运行从属服务器时，它工作正常。有什么想法吗？
