WP Mail SMTP Problem with sending emails

Hi i have a problem with setting up WP Mail SMTP plugin, my website is hosted to GoDaddy shared hosting and i use godaddy SMTP informations. When i try to send test email i get this error:

Versions:
WordPress: 4.9.6
WordPress MS: No
PHP: 5.6.36
WP Mail SMTP: 1.2.5

Params:
Mailer: smtp
Constants: No
ErrorInfo: Message body empty
Host: relay-hosting.secureserver.net
Port: 25
SMTPSecure: string(0) ""
SMTPAutoTLS: bool(false)
SMTPAuth: bool(false)

Server:
OpenSSL: Yes
Apache.mod_security: No
SMTP Debug:
[empty]

Here u can see which settings i set: https://snag.gy/VCRF06.jpg
This are standard SMTP settings for GoDaddy shared hosting.

Any idea what is going on?

Thank you.
