Solution:

1. Type hostname on server 
2. sudo su root
3. vi /etc/hosts
4. Change from --> 127.0.0.1 localhost locahost.localdomain localhost4 localhost4.localdomain4
5. To --> 127.0.0.1 HostName HostName.localdomain localhost4 localhost4.localdomain4
6. ex- 127.0.0.1 OIG OIG.localdomain localhost4 localhost4.localdomain4
