Not able to send notifications

[hrdy90]

Hi. Recently installed EspoCRM. All works great, incoming and outgoing mails. Only thing left that is not working is mail notifications. According to system requirement all is good.

I have ensured that cron is running since all other is working fine. Server logs does not state anything and thinks everything is Success.

But data/logs/ throws the following lines:
[2021-04-25 02:56:04] ERROR: EmailNotification: [0] Port must be greater than 1; received "0" [] []
[2021-04-25 02:56:04] ERROR: EmailNotification: [0] Port must be greater than 1; received "0" [] []
[2021-04-25 02:56:04] ERROR: EmailNotification: [0] Port must be greater than 1; received "0" [] []
[2021-04-25 02:56:04] ERROR: EmailNotification: [0] Port must be greater than 1; received "0" [] []

I have double and tripple checked all settings in:
Outbound Emails
Group Email Accounts
Personal Email accounts

Also, just to be sure I tried changing the default port 587 to something else just to change it back just in case it was not written to some config file.

Checking the data/config.php file all looks good as well:
'smtpServer' => 'smtp.gmail.com',
'smtpPort' => 587,
'smtpAuth' => true,
'smtpSecurity' => 'TLS',
'smtpUsername' => 'xXxXxXx',
'smtpPassword' => 'xXxXxXx',

Did some googling and found another topic with same error code but he had forgot to enable SMTP:

Out of ideas here, please help.

Hello,

Carefully check the IMAP and SMTP settings in your CRM, and don't forget to enable all permissions on your google or outlook account.
Check cron setting, cron is responsible for notifications.

Hello hrdy90,
Email Notifications sends by Outbound Emails in Administration. Neither Personal nor Group Email Accounts do that.
Try to set-up SMTP configs for the SSL connection instead of TLS and check the notifications again https://support.google.com/a/answer/176600?hl.
