I am totally lost in the ¨create your own website¨world. I REALLY need some help. I have followed MANY tutorials about wordpress and hosting sites, and I still get the message website is temporarily unavailable¨This website is temporarily unavailable, please try again later¨…what am i doing wrong??

Steps:
1) I bought my domains in godaddy
2) I downloaded wordpress
3) bought a wordpress theme from forest themes and successfully installed it
4) I bought the web hosting in host gator
…after reading some issues in the forum, I did the following:
1) went to go daddy to unable the ¨forward to¨option, change the host names, and the name servers with the information received from host gator
still I cannot access to my wordpress/wp-admin link. The domain is: https://www.groupbangarang.com
PLEASE HELP!!!
