Problems with Google Mail

I have a problem with emails I can't configure Gmail parameters. I entered the Gmail configuration parameters in the traccar.xml file.

    <entry key = 'mail.smtp.host'> smtp.gmail.com </entry>
    <entry key = 'mail.smtp.port'> 587 </entry>
    <entry key = 'mail.smtp.starttls.enable'> true </entry>
    <entry key = 'mail.smtp.from'> +++++++++ @ gmail.com </entry>
    <entry key = 'mail.smtp.auth'> true </entry>
    <entry key = 'mail.smtp.username'> +++++++++ @ gmail.com </entry>
    <entry key = 'mail.smtp.password'> ++++++++ </entry>

I restarted Traccar but the service does not start.

This is the error log.

Can you help me understand where I'm wrong.

Thanks

    <entry key='mail.smtp.password'>xxx</entry>

the password is an application password because two-step authentication must be activated...
it work for me

Your log indicates that the service is running.

The service is offline after making the change when i try to access the machine it tells me unreachable.
I try to change the password.

unfortunately, even if the settings are changed, the machine does not start
Any other suggestions?

Yes, you have an invalid XML file.

I entered the configuration for sending emails I can't understand where the error is.
