Pearl script Net::SFTP authentication error

Code:
#!/usr/local/bin/perl -w
use Net::SFTP;
use File::Copy;
 
my $user=(getpwuid($<))[0];
my $server = "servername";
print "user - $user  server - $server \n";
my %args = ( user => "$user", ssh_args => {port=> 'portnum'} );
$args{debug} = 1;
$args{user} = "user";
my $sftp=Net::SFTP->new($server, %args) or die "could not open connection to $server\n";

I am getting error

for the same server when i had done sftp using command line its working properly
Code:
"sftp -o Port=PORTNUM user@server"

created public key RSA and stored in id_dsa and id_rsa, tried giving identify_file path to id_rsa, but same error i am getting.
I cannot use foreign or chilkat as library is not available, our production team is not ready to upgrade, i am using perl-5.8.8
please suggest any code changes for pearl script.
