There was a problem sending the test email

[Payl8r]

Hello,
I've tried setting up the mailer using Gmail as per your screenshot at https://docs.formtools.org/modules/swift_mailer/gmail/

However, I keep getting this error:

There was a problem sending the test email: Connection could not be established with host smtp.gmail.com [Cannot assign requested address #99]

I've tried every combination of options and even with a different account.
I know SMTP relay is enabled on both accounts as I use it for other applications.

Any idea what the problem is please?
Thanks in advance
Dan

Dan, I have the same problem.

I want messages from my website's contact form to do directly to my email address.

I've tried setting it up using Gmail AND I've tried using my domain server's SMTP server.

I even spent 30 minutes with Inmotion Hosting's Tech Support guy trying to fix this.

Is it a PHP Version mismatch?

Please someone reply as this is driving me nuts!
