APEX

Env: OCI ADW
APEX: 23.1

I am trying to use the new (amazing) feature of Push Notification

Code:
apex_pwa.send_push_notification (
p_application_id => :APP_ID,
p_user_name => <USER>
p_title => 'Notification Title2',
p_body => 'Notification Body2' );
Code is working well.
However, all the notifications are queuing up with ORA-24247

I've done the security code in the PWA app

declare
    l_principal varchar2(20) := 'APEX_230100'; -- Replace with current APEX user
    l_hosts apex_t_varchar2  := apex_t_varchar2(
                                    '*.push.apple.com',
                                    '*.notify.windows.com',
                                    'updates.push.services.mozilla.com',
                                    'android.googleapis.com',
                                    'fcm.googleapis.com' );
begin
    for j in ( select column_value as hostname from table(l_hosts) ) loop
        dbms_network_acl_admin.append_host_ace (
            host       => j.hostname,
            lower_port => 443,
            upper_port => 443,
            ace        => xs$ace_type(
                              privilege_list => xs$name_list('connect'),
                              principal_name => l_principal,
                              principal_type => xs_acl.ptype_db) );

        dbms_network_acl_admin.append_host_ace (
            host       => j.hostname,
            ace        => xs$ace_type(
                              privilege_list => xs$name_list('resolve'),
                              principal_name => l_principal,
                              principal_type => xs_acl.ptype_db) );

        dbms_network_acl_admin.append_host_ace (
            host       => j.hostname,
            lower_port => 443,
            upper_port => 443,
            ace        => xs$ace_type(
                              privilege_list => xs$name_list('http'),
                              principal_name => l_principal,
                              principal_type => xs_acl.ptype_db) );
    end loop;
end;

But the issue still exists… I cannot figure out a way to solve it.

Any ideas about what I am doing wrong here?

Again, this is an ADW Free plan env.

Thanks,
