أستخدم خدمة [mailgun.com](http://mailgun.com) لإرسال البريد، لكن بروتوكول SMTP الذي قمت بإعداده وفقًا للبرنامج التعليمي لا يعمل. لا يمكنني حتى إنهاء التسجيل كمسؤول سجل الدخول المشترك/المستقل/log/rails/production.log ```plaintext Started GET "/finish-installation/register" for 54.151.175.32 at 2023-01-11 18:37:43 +0000 Processing by FinishInstallationController#register as HTML Rendered finish_installation/register.html.erb within layouts/finish_installation (Duration: 8.2ms | Allocations: 750) Rendered layout layouts/finish_installation.html.erb (Duration: 33.4ms | Allocations: 3008) Completed 200 OK in 54ms (Views: 36.7ms | ActiveRecord: 0.0ms | Allocations: 4064) Started POST "/finish-installation/register" for 54.151.175.32 at 2023-01-11 18:37:45 +0000 Processing by FinishInstallationController#register as HTML Parameters: {"authenticity_token"=>"rxWiZY9rnT7TRGYXw *****************************iBAFuOoz7pQA", "email"=>"************************* @gmail.com", "username"=>"youyou", "password"=>"[FILTERED]", "commit"=>"Register"} start Redirected to https://bbs.doublekm.xyz/finish-installation/confirm-email Completed 302 Found in 47ms (ActiveRecord: 0.0ms | Allocations: 2579) Rendered layouts/email_template.html.erb (Duration: 1.1ms | Allocations: 35) Started GET "/finish-installation/confirm-email" for 54.151.175.32 at 2023-01-11 18:37:45 +0000 Processing by FinishInstallationController#confirm_email as HTML Rendered finish_installation/confirm_email.html.erb within layouts/finish_installation (Duration: 2.5ms | Allocations: 380) Rendered layout layouts/finish_installation.html.erb (Duration: 21.1ms | Allocations: 2643) Completed 200 OK in 26ms (Views: 22.8ms | ActiveRecord: 0.0ms | Allocations: 3240) Job exception: Net::SMTPUnknownError fail ``` إعدادات SMTP ```plaintext DISCOURSE_SMTP_ADDRESS: smtp.mailgun.org DISCOURSE_SMTP_PORT: 587 DISCOURSE_SMTP_USER_NAME: postmaster@sandboxba2 ****************** d8f.mailgun.org DISCOURSE_SMTP_PASSWORD: "4223 ********************************************* 5f57" #DISCOURSE_SMTP_ENABLE_START_TLS: true # (optional, default true) DISCOURSE_SMTP_DOMAIN: sandboxba22 ************************ 8d8f.mailgun.org DISCOURSE_NOTIFICATION_EMAIL: no-reply@sandboxba22 *************** d8f.mailgun.org ## If you added the Lets Encrypt template, uncomment below to get a free SSL certificate LETSENCRYPT_ACCOUNT_EMAIL: me@example.com ``` ```plaintext [root@GreenCloud discourse]# telnet smtp.mailgun.org 587 Trying 34.83.33.178...
