"There was a problem sending your email. Please review your settings" when sending test email in Qlik Cloud SMTP configuration

[Daniele_Purrone]

When setting up an email server in Qlik Cloud under Management Console --> Settings, sending of test emails fail with "There was a problem sending your email. Please review your settings"

Environment

• Qlik Sense Business 
• Qlik Cloud 

Resolution

This might be due to a series of factors, like incorrect Security setting, requirements on the SMTP server side and more.
To troubleshoot this:

1. enable the browser's developer tools 
2. send the test email again.
3. go to the Network tab of the developer tools
4. open the Response to the send-test-email item
5. investigate the resulting error message with your mail server vendor support
