URL error on google search with Laravel

Personally, I have the following problem I developed this site here , if you go google and enter pass well contests him appears in the search engine quietly, but in the desktop version. Now if you try to access the mobile version on google it finds the site more instead of using the URL default that would be www.passebemconcursos.com.br it does this m.passebemconcursos.com.br and this causes the page not to open anymore if I go and type in the search bar in the browser URL correct it opens quietly the same problem is being when do the search of the site in google itself. I'm using laravel I'd like to know if you can convert this URL to the correct one.
