Net::SMTPAuthenticationError

Seems pretty clear. Something is wrong with your username or password.

Have a look at Troubleshooting email on a new Discourse install for how to get mail working.

Jay, thank you!

The error appeared because my sever provider supports only AUTH LOGIN, when Discourse uses AUTH PLAIN. I used another SMTP provider and resolved this issue. Now everything works fine.
