No internet connection with bridge adapter

I had internet connection inside my virtual box but after not using it for over a week I am not having internet connection. (Similar question to the question posted on ask ubuntu)

The things that come to my mind are:

  1. Reset router
  2. Enabled serial port between my 2 virtual machines

I've followed the steps suggested by other answers in stack-exchange and none did work. (when I switch to NAT I have internet connection but for debugging purposes I must have it as bridge-adapter for having different ips for each VM

Host Machines: Win10
Here are the settings of the VM: (vm are running linux 4.17.0v kernel)
