Après l'installation, Curl peut envoyer des e-mails, mais Discourse ne le peut pas. Aidez à corriger ?

I’ve gone through the steps here: Troubleshooting email on a new Discourse install

Without much luck. running discourse-doctor gives me the same output : Net::ReadTimeout,
that I also see in shared/standalone/log/rails/production.log
