If you have physical acess to the server via console ,login to rhe server
and execute ifconfig to c tje ip adsress and interface its listng .....
Then execute ethool (interface).... In the output check out link detected
status ..... If it says no then there is some phy problem either cable or
the uplink to network device .....

Hi Srini,
Possible reasons:
1.
Server is not reachable via network.
Try ping the server.
*unable to ping (request time out)*
2.
openssh server is not running in server.
install and start it
3.
ssh running in different port other than 22
check the port ssh is running.
*no,it is running in port 22 only*
4.
Firewall is blocking port 22
check the firewall rules.
*no firewall is not blocking. iptables is not running..there is no firewall
block.suddenly from today it happens,till yesterday able to logon to that
server.*
Some problem in physical connectivity i think.
Thanks,
HariPrasadh
