Hi,
In the master pg_hba.conf file, standby server hostname name is not being read even with the domain name, but server ip is working fine.
output of /etc/hosts is given below
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
<server ip> <hostname>.domainname hostname
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
<server ip> <hostname>.domainname hostname
Regards.

I put the ip of standby back in pg_hba.conf file of the master server and replication got started, though in the standby server I mentioned the hostname of master in primary_conninfo on the standby side.
So why is the master not reading the hostname of standby ? What am I missing here ?
You'd have to show us pg_hba.conf and /etc/hosts.My guess, though, is that you're not taking the domain name into account.
