[Problem] Duplicate homepage

Site URL: https://www.bestcsgocasino.com/

Hi!

I'm having some problems with indexing my homepage on google and I think I found the problem, 
but I am not sure how to solve it. Maybe some of you could help me out? 

When I sent my website for indexing, google search console gave me the following error: 
"Duplicate: the given webbadress has not been selected as canonical"
This error was only given for my homepage, bestcsgocasino.com/home

I think the reason the error occured is because these two URL's bestcsgocasino.com/home & bestcsgocasino.com

are both the exact same page, they are both my homepage. How do I solve this issue? Do I 301-redirect 

from "bestcsgocasino.com" to --> "bestcsgocasino.com/home"? 

Thankfull for any response!
