Здравствуйте,
в настоящее время мы используем Discourse v2.3.2 и столкнулись с необычной проблемой. Если я создаю тему или сообщение со ссылкой на домен форума (без пути), я не могу сохранить его из-за внутренней ошибки сервера (Internal Server Error).
Предположим, что URL вашего форума — `https://www.my-forum.com`, и я публикую что-то вроде:
„`Пожалуйста, загляните на нашу [главную страницу](https://www.my-forum.com)`"
Результат следующий:
Как только я редактирую ссылку на `[…] [главную страницу](https://www.my-forum.com/latest)` или `[…] [главную страницу](https://www.my-forum.com/categories)`, всё начинает работать нормально.
Вот логи:

Как вы написали, код ищет путь после домена.
Может быть, завершающий слэш поможет?

К сожалению, нет. Хорошая мысль, но меня бы это удивило. Особенно учитывая, что любые другие URL работают отлично и без слеши в конце, например `[homepage](https://google.com)`.

Вы используете сторонние плагины?

Привет,
извините за поздний ответ.
Да, мы используем некоторые плагины (сторонние). Вот они:
[discourse-adplugin](https://github.com/discourse/discourse-adplugin)
[discourse-solved](https://github.com/discourse/discourse-solved)
[discourse-user-notes](https://github.com/discourse/discourse-user-notes)
[procourse-static-pages](https://www.github.com/procourse/procourse-static-pages)
а также несколько собственных разработок, которые мы уже отключили.

Здравствуйте,
чтобы завершить этот вопрос. Мы обнаружили ошибку в применённом нами патче. У нас возникла та же проблема, что и описана [в этой теме](https://meta.discourse.org/t/invalid-input-for-update-ip-address/77085), поскольку мы используем Azure Application Gateway V1.
[В этом сообщении](https://meta.discourse.org/t/invalid-input-for-update-ip-address/77085/17?u=klopsknoedel) я описал, что мы сделали для обхода этой проблемы.
В любом случае. Похоже, что `request.ip` равен `nil`, если вы создаёте ссылку на собственное имя хоста, поэтому наш обходной путь не работает. Мы исправили это, обернув код в блок `begin…rescue…end` следующим образом:
```ruby
begin
ip_port_split = request.ip.split(':')
ip_only = ip_port_split.first
rescue
ip_only = request.ip
end
```
Мы с нетерпением ждём следующего обновления/релиза `rack`, так как он должен/будет корректно обрабатывать заголовки `x-forwarded-for`.
Спасибо за ваше время и с наилучшими пожеланиями.
Саша
