Hi, All of my emails suddenly stopped sending. No clue how this happened, no changes were made. Sidekiq: Jobs::HandledExceptionWrapper: Wrapped EOFError: end of file reached Jobs::HandledExceptionWrapper: Wrapped Errno::ECONNRESET: Connection reset by peer Jobs::HandledExceptionWrapper: Wrapped Errno::ECONNRESET: Connection reset by peer - connect(2) for "in-v3.mailjet.com" port 587 3 different emails won’t send, on the dashboard, it says “There are 3 email jobs that failed. Check your app.yml and ensure that the mail server settings are correct. See the failed jobs in Sidekiq.” app.yml: env: LC_ALL: en_US.UTF-8 LANG: en_US.UTF-8 LANGUAGE: en_US.UTF-8 UNICORN_WORKERS: 4 DISCOURSE_HOSTNAME: mydomain.com DISCOURSE_DEVELOPER_EMAILS: ‘admin@mydomain.com’ DISCOURSE_SMTP_ADDRESS: in-v3.mailjet.com DISCOURSE_SMTP_PORT: 587 DISCOURSE_SMTP_USER_NAME: usrname DISCOURSE_SMTP_PASSWORD: “psword” DISCOURSE_SMTP_DOMAIN: mydomain.com DISCOURSE_NOTIFICATION_EMAIL: noreply@mydomain.com LETSENCRYPT_ACCOUNT_EMAIL: me@example.com All emails were working until a random point, didn’t make any changes but errors just started. Discourse Doctor says “Connection reset by peer This is not a common error. No recommended solution exists!” Would appreciate any help.

@pfaffman @Arkshine Thank you to both for your help, turns out it was a problem with Mailjet. Switched to a different mail provider and it’s working fine ever since. Thanks!

Hi, Did you check your firewall settings? From mailjet side, it seems everything is fine: https://status.mailjet.com/ I would still check if something changed in the configuration.

Check your mailjet account. My best guess is an issue with your account.
