The idea is that you check the logs to see what is wrong exactly. Horizon is supposed to be a frontend for the users of the cloud, and not a debugging tool for its operators. We can't simply forward every error message to the user, because we are never sure if it contains some technical details that the user shouldn't have access to, and because it's not translated.
