Hi guys, need help, I'm trying to send email from

my app using email (gmail workspace) and password, it used to work on Ubuntu 24 (python 3.13) for the last month, until last week, it stuck on STARTTLS error.

smtplib.SMTPNotSupportedError: STARTTLS extension not supported by server.

The exact code, copied to Windows env on python 3.13, just work perfectly, is there something that required some tweaks within the Ubuntu env?
