Hello Community! after installing discourse I am struggling with email setup. I did necessary setup with mailgun. Sending email to admin@domain.com from my mail.google.com (normal gmail) is working fine. But when I use it with app.yml config, I get following error and did not receive an email. It is very 1st email, I am not able to sign up for my forum. I think it is due to plain auth. I read it on one of thread. But I don’t know about solution. Discourse doctor: [תמונה] app.yml [תמונה] I have taken look over some other smtp threads in this problem. UNEXPECTED ERROR Net::SMTPAuthenticationError Port 443 of computer does not appear to be accessible using Unable to send mails using Discourse Cannot send email - problem with port 465 - #9 by RGJ Yet other SMTP 587 port email various errors Smtp doctor test using port 465 even though its configured to use 2525 - #11 by Bryan_Joseph Thanks for your time and support.

I’ve gotten stuck by that one too!

Okay, Found the solution. I was using US mailgun server but actually it is EU. So it was mistake.
