SMTP (Sendgrid) not working

Description

We use SendGrid on a whole host of platforms, no issues. We usually use a dedicated API key and setup the integration via SMTP.

I cannot get emails to be sent and the logs do not even show a single error while trying to send the test email.

I ready elsewhere that after changing SMTP settings you have to restart rocket chat, so I’ve done that a number of times
