Last modified: August 21, 2016 --- # "string(22) "SMTP connect() failed." * [Wee.Wesley](https://wordpress.org/support/users/weewesley/) * (@weewesley) * [11 years, 11 months ago](https://wordpress.org/support/topic/string22-smtp-connect-failed/) * My website is [http://www.sginvestguru.com](http://www.sginvestguru.com) I’ve been trying and trying with the same domain name, and even tried with gmail smtp settings. But i keep on getting this error….” string(22) “SMTP connect() failed.”” Does anyone know what error I have? * *The main reason for this setup is because all my forms are unable to send email out. This applies to new subscribers or editors that i create manually under the Users section too. * ``` Test Message Sent The result was: bool(false) The full debugging output is shown below: object(PHPMailer)#126 (69) { ["Version"]=> string(5) "5.2.7" ["Priority"]=> int(3) ["CharSet"]=> string(5) "UTF-8" ["ContentType"]=> string(10) "text/plain" ["Encoding"]=> string(4) "8bit" ["ErrorInfo"]=> string(22) "SMTP connect() failed."
