SMTP connect() failed

Replies: 0

Hi,

I hope someone can help with this?
I am new to webdesign and all things wordpress and I’m having a little trouble getting the WP Mail SMTP plugin to work with ‘Other SMTP’ selected and using smtp.office365.com as the host.

I have populated all of the fields with the correct information and I know that the credentials are correct.

Sending a test email throws this error report right back at me…

Versions:
WordPress: 5.8.3
WordPress MS: No
PHP: 7.4.26
WP Mail SMTP: 3.2.1

Params:
Mailer: smtp
Constants: No
ErrorInfo: SMTP connect() failed. https://github.com/PHPMailer/PHPMailer/wiki/Troubleshooting
Host: smtp.office365.com
Port: 587
SMTPSecure: tls
SMTPAutoTLS: bool(true)
SMTPAuth: bool(true)

Server:
OpenSSL: OpenSSL 1.1.1d 10 Sep 2019
Apache.mod_security: No

Debug:
Email Source: WP Mail SMTP
Mailer: Other SMTP

SMTP Debug:
2022-02-08 19:55:32 Connection: opening to smtp.office365.com:587, timeout=300, options=array()

2022-02-08 19:55:35 Connection failed. Error #2: stream_socket_client(): unable to connect to smtp.office365.com:587 (Network is unreachable) [/home/fs7dfeztrlrj/public_html/transporterheaven.co.uk/wp-includes/PHPMailer/SMTP.php line 388]

2022-02-08 19:55:35 SMTP ERROR: Failed to connect to server: Network is unreachable (101)

I am using GoDaddy as my webhost and they haven’t been able to offer a solution.
I have enabled SMTP on the email account.

Am I doing anything wrong and can someone educate me on the significance of the SMTP.php file (line 388)?
Opening SMTP.php and looking at line 388 gives me this… ‘$host . ‘:’ . $port,’

Many thanks in advance for any help that can be offered.
