Spring boot (2.2.4.RELEASE) на docker зависает при загрузке, если только network_mode: host

У меня есть докернизированное приложение Springboot, если я запускаю образ на своем компьютере (ubuntu), все отлично работает с docker сетевым режимом по умолчанию, как только я запускаю образ на корпоративном сервере (VPS) с настройками по умолчанию, он зависает при запуске и остается там навсегда.

Я попытался настроить свою пользовательскую сеть на уровне docker, использовать ip, hostnames и не повезло , кто-нибудь испытывал такое же поведение?

Мне нужно было установить docker MTU демона таким же, как и сетевую карту.

IP-шоу 

    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> **mtu 1450** qdisc pfifo_fast state UP mode DEFAULT group default qlen 1000
3: docker0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc

отредактировано / etc / docker / daemon. json

  "mtu": 1450
}

Проблема решена. Сложно, когда я сделал удаленную отладку, я заметил, что он блокировал чтение сокетов, оттуда Google был моим другом.
