You will have to actually review the coding in the "/home/******/public_html/.htaccess" file to determine which one is causing the redirect loop.

As a test you can comment our each rule (one-at-a-time), until the wild card redirect works.

Alternately, I found a forum post where they provide possible solutions on how to redirect all wildcard subdomains to root domain.

Like most coding solutions, you will have to test as you work until you find a solution that fits your needs.
