Try the following "commands" from a Command Prompt on your guest. I've included a sample output, with only the parameters that you should be focusing on:

$ ifconfig
enp0s3    Link encap:Ethernet  HWaddr 08:00:27:40:51:1a  
          inet addr:10.0.2.15  Bcast:10.0.2.255  Mask:255.255.255.0

$ route -n
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
0.0.0.0         10.0.2.2        0.0.0.0         UG    100    0        0 enp0s3

or if you prefer "nmcli":

$ nmcli d show
GENERAL.DEVICE:   enp0s3
GENERAL.HWADDR:   08:00:27:40:51:1a   <-- all VirtualBox NICs start with that number
IP4.ADDRESS[1]:   10.0.2.15/24
IP4.GATEWAY:      10.0.2.2
IP4.DNS[1]:       1.1.1.1

Then, once you have the key values, try the following commands:

$ ping <DefaultGateway>             <-- tests your connectivity
$ ping 1.1.1.1                      <-- tests outgoing/DNS connectivity
$ ping download.virtualbox.org      <-- tests name resolution

Report any misconfiguration, or any errors from the "ping" commands.

If you can "ping <DefaultGateway>", if you can "ping 1.1.1.1", if you can "ping download.virtualbox.org", VirtualBox is working as it should. You should look elsewhere for your networking connectivity. Look in your host for firewalls, proxies, antivirus filters, web-cleaning applications, redirectors, etc.
