Получил «ERR_CONNECTION_TIMED_OUT» при запуске docker для версии Windows:
Docker version 18.06.1-ce, build e68fc7a.
Использование контейнеров Linux (настройки мастера установки по умолчанию).Docker inspect containerID выдает: "IPAddress": "172.17.0.2", Сетевые настройки: 

"NetworkSettings": {
    "Bridge": "",
    "HairpinMode": false,
    "LinkLocalIPv6Address": "",
    "LinkLocalIPv6PrefixLen": 0,
    "Ports": {
        "8080/tcp": null

Состояние: 

"State": {
    "Status": "running",
    "Running": true,
    "Paused": false,
    "Restarting": false,
    "OOMKilled": false,
    "Dead": false,
    "Pid": 2918,
    "ExitCode": 0,
    "Error": "",

Подключение к Docker Tomcat с помощью: http://172.17.0.2:8080 Сообщение об ошибке: ERR_CONNECTION_TIMED_OUT

Нет прокси в настройках докера.

Ясно, что сопоставление портов не выполнено должным образом: 

 "Ports": {
        "8080/tcp": null
  }

null означает, что док-порт внутри порта 8080 не сопоставлен с соответствующим снаружи.

, когда порт несопоставленный, не будет никакого способа получить к нему доступ по URL, и вы получите ERR_CONNECTION_TIMED_OUT

, так как не ясно, как вы запустили свой контейнер, я могу только предложить вам простой и правильный способ портасопоставление будет: 

docker run -it --rm -p 8080:8080 tomcat:latest

, где внешний порт 8080 сопоставлен с внутренним портом Docker Tomcat 8080, тогда вы можете получить к нему доступ по localhost: 8080
