Internet connection lost on Docker host


I’m running Docker 19.03 on Windows Server 2019 hosted by Windows Server 2016.

I’m currently running 40 containers on this VM and sometimes it loses the internet connection for God knows how long it will be gone, and gets back later.

I’m suspecting containers are geting heavy networking traffics, and there are actually networking congestions.

is there any way I can diagnose this? and how should I resolve this issue? will giving more CPU/RAM resources fix this issue?

Thanks in advance.
