Autoresponder "Sender Email" - Blocked by Google

Hello Jotform, not sure if I'm doing this wrong, but I configured Autoresponder "sender email" with GMail's server info, but I keep getting a message that it's been blocked.

I followed this link: https://www.lifewire.com/what-are-the-gmail-smtp-settings-1170854

and configured it with TLS... but the "blocked" message persists.

What can we do to fix this?
