Here is what I’m trying to do:

SELECT utl_http.request('openexchangerates.org',NULL,'file:C:/Users/Uchih/OneDrive/Escritorio/wallet','password123') from dual;

I need to make a http.request, to test a connection to that web site to use a webservice from that page.
And also I already have configured my wallet with all the certificates of the web page.
So the wallet shouldn’t be a problem

And here is my acl code:

BEGIN

DBMS_NETWORK_ACL_ADMIN.CREATE_ACL(
    acl => 'otro_acl.xml',
    description => 'otra prueba',
    principal   => 'APEX_220200',
    is_grant    =>  TRUE,
    privilege   => 'connect'
);


END;

BEGIN
    DBMS_NETWORK_ACL_ADMIN.ADD_PRIVILEGE(
        acl => 'otro_acl.xml',
        principal   => 'APEX_220200',
        is_grant    => TRUE,
        privilege   => 'resolve'
    );

END;


BEGIN
    DBMS_NETWORK_ACL_ADMIN.ASSIGN_ACL(
        acl =>  'otro_acl.xml',
        host    => 'openexchangerates.org',
        lower_port  => NULL,
        upper_port  => NULL
    );

END;

Also I assigned te privileges to my hr user:

BEGIN
    DBMS_NETWORK_ACL_ADMIN.ADD_PRIVILEGE(
        acl => 'otro_acl.xml',
        principal   => 'HR',
        is_grant    => TRUE,
        privilege   => 'connect'
    );

END;




BEGIN
    DBMS_NETWORK_ACL_ADMIN.ADD_PRIVILEGE(
        acl => 'otro_acl.xml',
        principal   => 'HR',
        is_grant    => TRUE,
        privilege   => 'resolve'
    );

END;

But I’m getting these errors:

ORA-29273: fallo de la solicitud HTTP
ORA-06512: en "SYS.UTL_HTTP", línea 1530
