gmail API – port 443

Hello,

I try configuring postman on a bluehost domain.
I configured the google API since the only open port is 443.

I have the message :
Postman will send mail via 🔐SMTP-STARTTLS to smtp.gmail.com:443 using OAuth 2.0 authentication.

I granted permission with Google, but when I send a test email I have a “connection timed out”

Here is the diagnostic test :
