Mesos Slave on Windows 2016. Not Connecting with Master - mesos

Question

My current set up is as follows:
Mesos Master — 10.20.200.300:14081 - RHEL 7
Zookeeper — 10.20.200.300:14080 - RHEL 7
Mesos Agent — 10.21.210.310:5051 - Windows 2016
The master is up & is able to connect to zookeeper. However, on starting the agent, even if the agent is connecting to zookeeper, it is not getting connected to the Master.
Master was started as systemd process with below paramters under /etc/mesos-master -
hostname - mymaster.mesos.com
quorum - 1
work_dir - /var/lib/mesos
advertise_ip - 10.20.200.300
advertise_port - 14081
Below are the logs from master, slave & zookeeper.

Does anyone know the reason for these?
I have tested the connectivity between slave -> master & master -> Slave & it was successful.

I got up the agents with below parameters -

Do we need to test any other connectivity or this error is for some other reason?

Answer 1

I would try this
Set hostname on slave (you can say hostname=10.21.210.310)
Check firewall on Windows machine. Allow incoming conections to 5051 port
