No ssh connection possible for spark slave

Question

I am connecting with ssh on a daily basis to a remote server with the command: ssh user_name@private_ip_address

I have installed spark on my linux and try to start a slave on the remote server after starting the master. So I put the remote server public ip address in my /etc/hosts file and I put the host name in the conf/slaves file in spark configuration. Then I run the command start_slaves.sh. The output is um1: ssh: connect to host um1 port 22: Operation timed out

What is the problem? What is wrong I followed many tutorial and did exactly what is mentioned. Why I am able to ssh without problem outside of Spark but it becomes a problem in Spark?
