wordpress inifinite redirect loop - wordpress

Question

My domain "walterscube.com" is point to a google cloud wordpress server http://xx.xx.xx.xx/. I use godaddy as my domain provider.
I changed my site address and wordpress address from ip to domain, because i want to see my domain name in the browser not my ip. The webpage will be in an infinite redirect lope between the ip and my domain. Can someone help what possibly causes this?
I already tried change all IP to domain in the database,
and i tried add to wp-config.php this lines
define('WP_HOME','http://walterscube.com/');
define('WP_SITEURL','http://walterscube.com/');
,with no result.
Thank you
Vince
*edit:
The server is the default google cloud launcher>WordPress, I did not change any settings.

Try running these queries in your DB to update your site's URL in the database. I would think that the constants you reference above should do it, but for thoroughness' sake, update these values, too.
UPDATE wp_options SET option_value = REPLACE (option_value,'http://xx.xxx.xxx.xx','http://walterscube.com');
UPDATE wp_posts SET guid = REPLACE (guid,'http://xx.xxx.xxx.xx','http://walterscube.com');
UPDATE wp_posts SET post_content = REPLACE (post_content, 'http://xx.xxx.xxx.xx', 'http://walterscube.com');
UPDATE wp_postmeta SET meta_value = REPLACE (meta_value,'http://xx.xxx.xxx.xx','http://walterscube.com');
The reason I reccommend this over checking your DNS records or anything else is that when I curl -H 'Host: walterscube.com' xx.xxx.xxx.xx -v, I get
* TCP_NODELAY set
* ...
> GET / HTTP/1.1
> Host: walterscube.com
> User-Agent: curl/7.54.0
> Accept: */*
>
< HTTP/1.1 301 Moved Permanently
< Date: Mon, 26 Mar 2018 13:10:29 GMT
< Server: Apache/2.4.10 (Debian)
< X-Powered-By: PHP/5.6.33-0+deb8u1
< Location: http://xx.xxx.xxx.xx/
< Content-Length: 0
< Content-Type: text/html; charset=UTF-8
(Which tells me that it's WordPress doing the redirecting, not the web server.)
Edit: ^ Quite an assumption, it turns out. The above likely just means that PHP's being executed by Apache. Not necessarily that WP's sent a 301 response!
