Send Email on Aruba not working

HI,
I'm trying to send emails using Aruba SMTP, it works locally but when I publish doesn't work.

I tried to view the output of : 

$email->printDebugger(['headers']);

but it returns nothing.

Does anyone know what the problem could be?,

i dont know but i use PHPMailer with my CI4 ; i like it because it works on local development on appache and live. I have to leverage its use using my own gmail account ; data from web form and rely it to the owner of the web .

I installed PHPMailer via composer. What i can tell you is that sometimes there is something the hosting has done or needs to do , so that it works live. So i told my hosting on one occasion hey its working fine local but not on your hosting. They came back yep we did this or that , try it now - and i found it worked.

in the contoller that processes data, pushes it through a spam check i have this bit :

Code:

                        catch ( \Exception  $e)
                                         {
                                                echo "something went wrong";    
                                         $data = [
                                                    'title'  => 'info',
                                                  
                                               'info'=>'something went wrong with sending message<br>  probably you have not entered credentials for lines 106 and 108 in Sendmail.php controller. <br><br>Hal says :  ' ,
                                               'infoException'=>$e->getMessage(),
                                               'date'=>$this->myDate,
                                                 ];
                                        
                                            echo view('info2', $data);
                                             die();

on some occasions its come back " could not authenticate" which hinted to me i got creds wrong for password of email. So maybe you could factoe something like that .The code nicely gets an error and puts it out on a view
