It seems like a redirect embedded within wordpress itself. You could start with checking the settings of WordPress Address (URL) after signing in to wp-admin at this link. If it didn’t work, you may have to modify wp-config.php-file per this wordpress.org help article and this very similar stackoverflow question.
Furthermore, and if the above didn't solve the issue, I recommend posting your question on stackoverflow.com where you have access to a large community of enthusiasts and experts to share ideas with and get support from. Please make sure to include all relevant details and error messages which would help the community troubleshoot.
