Does it give an error when sending email via SMTP server?

Question

Yii

Doesn't send email via SMTP server, on Yii2 framework. It seems that everything is set correctly in the Open Server settings. Writes that
"Failed to authenticate to the SMTP server with the username "[email protected]" using 3 possible means of authentication. The LOGIN author returned the expected response code 235, but received the code "535" with the message "535-5.7 .8 Username and password not accepted." Has anyone come across this problem please let me know!
