You could try a different approach such as:

my $soap = SOAP::Lite->uri($uri)->proxy($proxyURL);

In your script:

#!/usr/bin/perl -l

use strict;
use warnings;
use SOAP::Lite;

my $uri = 'http://www.example.com';

sub check_result {
    my ( $self, $code, $IP, $PORT ) = @_;
    my $proxyURL = "http://$IP:$PORT/REMOTE_SOAP";

    my $soap = SOAP::Lite->uri($uri)->proxy($proxyURL);
    $soap->autotype(0);
    $soap->default_ns('http://REMOTENAMESPACE/namespace/default');
    $soap->proxy->timeout(15);
 
    $soap->on_fault(
        sub {
            my ( $soap, $res ) = @_;
            eval { die ref $res ? $res->faultstring : $soap->transport
+->status };
            return ref $res ? $res : new SOAP::SOM;
        }
    );

    my $som =
      $soap->call( "remote_function", SOAP::Data->name('Entry1')->valu
+e($code),
      );

    return $som->paramsout;
}
