Server error in comments

Hello to all, I’m quite new in this world.

I’m having this problem when I write and sent a comment (gateway theme)
must be something not specified in the domain, zone record?
any clue will be very appreciated.

Server Error

Sorry, something went terribly wrong!

0 - Failed to authenticate on SMTP server with username “admin” using 2 possible authenticators. Authenticator LOGIN returned Expected response code 235 but got code “535”, with message "535 Incorrect authentication data " Log data: ++ Starting Swift_SmtpTransport EHLO designemergente.com AUTH LOGIN YWRtaW4= QW5ha2VuYTIxIQ==

For further details please review your logs/ folder, or enable displaying of errors in your system configuration.

Is your email.yaml setup to your smtp? Your smtp username is really admin?

Hello Duceduc,
I created an email account in cpanel
and set the email.yaml thorugh the admin panel.
it.s looks I did some progress:

0 - Connection to mail.designemergente.com:465 Timed Out Log data: ++ Starting Swift_SmtpTransport !! Connection to mail.designemergente.com:465 Timed Out (code: 0)

For further details please review your logs/ folder, or enable displaying of errors in your system configuration.

do you have any clue?
thanks
Carlos.

Port 465 was given to you from your host? Try different ports 25, 587.

Thanks Duceduc,
I changed to port 25 and localhost and it’s I dont have the error anymore, but It doesn’t send the email
best
C,

Have you checked your spam box?

Hi, Duceduc.
It was nothing in my spam box. I found a silly mistake in the code: in the form.md appear:
email:
from: ‘{{ config.plugins.email.from }}’
to:
- ‘{{ config.plugins.email.from}}’ //<here
I changed to
email:
from: ‘{{ config.plugins.email.from }}’
to:
- ‘{{ config.plugins.email.to}}’

and worked perfect!
thanks
Carlos
