Change main blog 1 from IP to domain

Hi,

Im trying to figure out how to change the sites pre installed setting from IP to my domain.

I really tried what what recommended.

wp-config:
define(‘RELOCATE’,true);
define(‘WP_HOME’,’https://derude.net’);
define(‘WP_SITEURL’,’https://derude.net’);

Not working, also without the first line.

Any suggestions how to get something working

Kind regards
