Subdomain module installation problem

I follow the readme.txt thoroughly to install it but I get an error in both "Web server" and "Drupal's inbound URL rewriting", I don't know why the HTTP_HOST: 127.0.0.1:1709 instead of the website domain.

it gives the following error while checking installation:
=========================
Web server Not working yet

HTTP request to http://subdomain-test.harreronline.org/subdomain/test returned the following result:
HTTP_HOST: 127.0.0.1:1709
QUERY_STRING: subdomain/test
REQUEST_URI: subdomain/test
SCRIPT_FILENAME: /home/harreron/public_html/index.php
drupal_get_normal_path: subdomain/test
Your web server erased the subdomain and rewrote subdomain-test.harreronline.org as harreronline.org.
Possible solutions:
Check your web server configuration and/or .htaccess for renegade redirect or urlrewrite statements
The subdomain module's .htaccess patch conflicts with the globalredirect module. You may need to disable one or the other if you are using Apache and globalredirect.

Drupal's inbound URL rewriting Not working yet

Array ( [0] => SUBDOMAIN TEST [1] => 127.0.0.1:1709 [2] => subdomain/test [3] => subdomain/test [4] => /home/harreron/public_html/index.php [5] => subdomain/test [6] => ) HTTP request to http://subdomain-test.harreronline.org/subdomain/test resulted in an internal Drupal path of subdomain/test. It should have been ~subdomain-test/subdomain/test

The custom_url_rewrite_inbound() function in settings.php is rewriting the internal path incorrectly. Did you patch settings.php? See readme.txt for instructions.

=========================
please help me to solve the issue.
