Domain map issue for single site

Good day,

I have a single site which use multiple domain, take note this is not a multi site.

I’m using this wpconfig to bypass the domain site
define(‘WP_SITEURL’, ….);
define(‘WP_HOME’, ….);

The problem is forcelogin plugin redirect the URL to the original one (if I disable the plugin it works ok), question how can I bypass this and use the domain URL and not the original domain URL?

thanks & regards,
