Localhost:8080 is not working and shows the error ERR_CONNECTION_REFUSED

Hi

I have installed Oracle DB 21c, APEX 24.1 and ORDS 24.2.3 successfully and I was able to run the APEX localhost and I setup workspace and users. But next day when I open the APEX through https://localhost:8080/apex and it is not succeded, it shows the error message "localhost refused to connect".

below are the findings when query the database.

below query returns no record

select comp_name, version, status from dba_registry
where comp_name = 'Oracle Application Express';

below query returns 0

select dbms_xdb.gethttpport () from dual;

Please let me know what would be the issue.

Thanks
