Just to clarify, you mention “http://my-portal.com:3000” address, does it mean you configured custom DNS record “my-portal.com”? Or you accessing it via VirtualBox IP address? Ensure that in VirtualBox settings you opened port 3000 and it is visible to Windows.
my-portal.com, I have mentioned in /etc/hosts file as below
127.0.0.1 my-portal.com
I have tried netstat -anlp | grep 3000 & netstat -anlp | grep 8080, but no output in ubuntu terminal.
I have not opened any ports in ubuntu running inside Oracle VirtualBox
