I wrote a code to get the answer from the api, which works correctly in Oracle 21. But in Oracle 11, even though I typed the acl codes, it still gives me the acl error.

Error:

ORA-29273: HTTP request failed ORA-06512: at “SYS.UTL_HTTP”, line 1339 ORA-29261: bad argument ORA-06512: at “APEX_200100.WWV_FLOW_WEB_SERVICES”, line 1284 ORA-29273: HTTP request failed ORA-06512: at “SYS.UTL_HTTP”, line 1130 ORA-24247: network access denied by access control list (ACL)

Code to get information from api:

declare
  vClob   clob;
  vDetectEMP number;
begin
  vClob := apex_web_service.make_rest_request(p_url => 'http://localhost:8002',
                                              p_http_method => 'GET');
  APEX_COLLECTION.CREATE_OR_TRUNCATE_COLLECTION(p_collection_name => 'API_RESPONSE');

  APEX_COLLECTION.ADD_MEMBER(
        p_collection_name => 'API_RESPONSE',
        p_C001 => vClob);
end;
