Mautic SMTP Test Email Error

Hi there,
I am going to set up my credential in Mautic for email sending but showing an error that " Failed to authenticate on SMTP server with username “email address” using 0 possible authenticators." anyone can help me to resolve this issue?

I have tried a lot of methods but still have not resolved this issue.
If anyone has faced this issue and resolved it then please help me in this regard.

Thank you!
