Connection Problems SMTP

Configuration
1

Hello,

I am having problems setting up the SMTP service.
The provider is called hetzner
https://docs.hetzner.com/de/konsoleh/account-management/email/setting-up-an-email-account/

Sending e-mails works under Node-Red:

However, I get the following settings:

notify:
  - platform: smtp
    name: "E-Mail send"
    server: "mail.your-server.de"
    sender: "[email protected]"
    port: 465
    timeout: 20
    encryption: tls
    verify_ssl: true
    username: "[email protected]"
    password: "YOUR_PASSWORD"
    recipient:
      - "[email protected]"
    sender_name: "Home Assistant"

The following Error:

    raise SMTPAuthenticationError(code, resp)
smtplib.SMTPAuthenticationError: (535, b'Incorrect authentication data')

The username and password are correct, as they also work with Node-Red.

What could be the problem?

Thanks

I have just changed the port from 465 to 587.

Then I get the following error message:

But what does that mean, the wrong SSL version?
