Email Template : Failed to use the email server to send the email, correct your configuration.
0
Hello. We're using the module EmailTemplate to send a few emails on an app. It worked for a few months and now all of a sudden it stopped working. The error that comes up is the one in the screenshot. Does anyone have any idea of what could be wrong? We suspect it's something in the server because the module hasn't been updated, but we're out of ideas of what it could be.
