Getting ERR_TOO_MANY_REDIRECTS on wp-admin.

Not able to get in admin side because wp-admin or wp-login.php giving redirect error.

“This page isn’t working

http://www.vision***veysqld.com.au redirected you too many times.” Please help.

The site was recently switched over to a new server, so whatever the issue probably has to do with a different configuration. But not sure.
