Dropped network connection

I came into work this morning, and could not ping or ssh to the guestOS, from a remote machine or the host OS. It worked yesterday, and I guess dropped sometime overnight. Restarting the guest OS (from within the guest OS) did not work. I had to shutdown the guest, close all virtualbox windows, and then restart everything, for it to work.

Any idea what the issue may be here?

Host OS: Ubuntu 18.04
Guest OS: Ubuntu 16.04
Virtualbox version: 6.08

Configured Network Adapter 2 as bridged network. Network Adapter 1 and 3 are disconnected.

Thanks!

You're not giving us too much to work with, but keep in mind that these things tend to happen, even in the real world. I'm having a problem for example with my physical Mint 19, where if it goes to sleep my 2 NICs think that the cable is unplugged! I have to actually reboot the whole system for it to work again! :shock:
