Connection could not be established

I have installed postfix, dovecot on my server. Now I am creating SMTP server and when validating server after adding the details I am getting the error:

  • Connection could not be established with host 172.104.171.192 [ #0]
    Log data:
    ++ Starting Swift_SmtpTransport
    !! Connection could not be established with host 172.104.171.192 [ #0] (code: 0)
I have also used subdomains in hostname, but still getting same error. Am I missing something?

Now I am getting this error when I switched my port from 587 to 25:

++ Swift_SmtpTransport started
>> MAIL FROM:<newsletter@mails.kitnek****ga.com>
<< 250 2.1.0 Ok
>> RCPT TO:<gaurav85.****pta@gmail.com>
<< 454 4.7.1 <gaurav85.****pta@gmail.com>: Relay access denied
!! Expected response code 250/251/252 but got code "454", with message "454 4.7.1 <gaurav85.****pta@gmail.com>: Relay access denied
" (code: 454)
>> RSET
<< 250 2.0.0 Ok

Please guide what could be the reason?

@gnine - google the error, it's not related to mailwizz but to your smtp server settings.
If you could post your delivery server settings screen shot(s), this might help.
