Email notifications not working in suitecrm

Email notifications not working in suitecrm. Please advice.

As already mentioned to you in our private chat, you definitely need to provide more information about your setup/configuration (I mentioned some examples). Without being more specific, we are probably not able to help.

Hi Team,

Thanks for the reply. Here below is the workflow to send a mail to new lead created on suiteCRM.

But it is working 10 -15 days ago. but now it is not working.

Please advice.

On the SuiteCRM log file, below error thrown.

" SugarPHPMailer encountered an error: SMTP Error: Could not authenticate."

Ola, bom dia, tudo joia??
Pelo que estou vendo os email são o maior problema para esse CRM.
particularmente é a parte que estou tendo mais dificuldade de entender.
