Configure UptimeKuma notifications to send email to gmail

I am configuring with smtp and using my app password but it still won’t connect properly. I have used this when running uptimeKuma as a virtual machine on other hardware. Is this a problem with this running under CasaOS?

All I get is “Unexpected Socket Closed”

Most probably the wrong port :

  • 465 for SSL/TLS ;
  • 587 for STARTTLS.
