Security in Joomla! 5.x • Can not connect to smtp.gmail.com Joomla 5

Hi,

For the last days I have tried to get the SMTP mail in Joomla 5 to work - but I get messages that it can not connect.

So my setup is:

Windows 10 pro PC (local pc)
Xampp installation 8.2.12
Joomla version 5.2.0

The openssl.dll is changed to be included in the PHP.ini files
API password on google validated and working.
And the setting in Joomla Server is setup to the documentation found various places on the internet:

SMTP - smtp.gmail.com
Port: 465
Security: SSL/TLS

There ar no firewall issues on the Windows 10 Pro pc - please see test form Zebmap app:

The log has been enabled on the Joomla site and here are the result:

I have test the SMTP setup on another Joomla installation on a different PC (Windows 10 Education) - and here it is working.

Do any have any clues to what is wrong ?
