connect AVDF host on virtualbox to the internet

I have been having issue connect to the IP of Audit Vault Server after the installation.

I'm using a Mac OS as host and I have successfully run AVDF on my Mac.

Here is my current configuration:

Network: Host-Adapter only

Memory: 8G RAM

Hard Drive: 300GB.

I ping the IP once the AV is running, but http://192.168.57.55 does not work.
