Приветствую!
ОЧЕНЬ прошу помощи. Я в ruby не силён и мне сложно понять, где ошибка.
Мы в процессе переноса серверов на другой VDS + недавно слетели все А-записи на домене
Есть сервер, имеющий внешний IP адрес и внутренний 10.1.1.12. на нём находятся домены api.server.info и server.info
error.log nginx с внешнего сервера
