OK I checked in my laptop too.
use server=ip_address. I am getting same problem when I used $server as domain name.(abc.com)

I will show you my test script.

linux@tuxworld:~$ cat test.sh
#!/bin/bash
server="1.1.1.1"
cmd="ls -la"
var=`ssh root@$server "$cmd"`
echo $var

linux@tuxworld:~$

This script is working for me

I am using ssh -t

it creates another tty

I am using parameter -t as i do not have root access on the server

I tested mine script it is working fine for me.

linux@tuxworld:~$ cat test.sh
#!/bin/bash

server=`nslookup abc.com|grep -A 3 abc.com|grep Address|awk '{print $2}'`
cmd="ls"
ssh -t username@$server $cmd

linux@tuxworld:~$

first of all check this command, are you able to get ip address with below command .if successful then run test.sh script.

nslookup abc.com|grep -A 3 abc.com|grep Address|awk '{print $2}'

but i can only use the dns name
Can you please suggest another way without resolving the dns to its corresponding ip

I tried to help you with all way ,apologize but system is in your control.

Give the answer of below two questions-

(1)Have you tried the script which I pasted and what was the output.Is it working or not.

(2)Does your server have multiple ip , just like if you do nslookup google.com .

OK check this, it is working from my end

linux@tuxworld:~$ cat test.sh
#!/bin/bash

server='your_domain_name.com'
cmd="ls"
ssh -t username@$server $cmd
