Hi there!

I tested on both versions but couldn't reproduce the error, could you share:

  • What environment your Metabase is running in (Docker, Cloud, etc)
  • If testing with port 587 instead of 465 fails as well
  • If you run ping smtp.gmail.com and grab the resolved IP and put in the Host field, if it fails as well
