Installing WordPress multisite on a domain with subfolder

Just moved my WordPress multisite from localhost to live server. The destination folder has two sub directories mydomain.com/dir1/dir2 I’m getting a ERR_TOO_MANY_REDIRECTS error can anyone help me out. I’ve made all the necessary url updates in the database. Thanks

wp-config

define('WP_ALLOW_MULTISITE', true );
define('MULTISITE', true);
define('SUBDOMAIN_INSTALL', false);
define('DOMAIN_CURRENT_SITE', 'mydomain.com/dir1/dir2');
define('PATH_CURRENT_SITE', '');
define('SITE_ID_CURRENT_SITE', 1);
define('BLOG_ID_CURRENT_SITE', 1);
