ubuntu server 16.04.3 IP Address Resolves Correctly but Webpage Does Not

[dmcgettigan]

So we cheated... we changed the IP address to 192.168.4.176 and now it works. I don't what the issue was but I got to my end result, thanks for the effort!

[Habitual]

Cheating is "creative" and +1
Issue was posts in table wp_posts has stored content pointing to http://192.168.4.176

WP_SITEURL and WP_HOME variables in db.
can be "cheated" also using

define('WP_HOME','http://domain.tld');
define('WP_SITEURL','http://domain.tld');

can be utilized in wp-config.php. negating the "reason" to alter another table.

wp_posts table has all the posted content still pointing to 192.168.4.176

something like export db > database.sql

cat database.sql | sed 's#http://192.168.4.176#http://10.11.79.3#g' > database2.sql

would "sanitize" the inplace data. You'd have to re-import database2.sql into the wordpress db and you should be golden.
