Your host by default cannot access a VM (see VB network types). What you might do is:
- change adapter 2 to host only adapter, ‘Virtualbox Host-Only Ethernet Adapter’)
- From the VB window, File > Host Network Manager and configure adapter manually instead of 192.168.56.1 to 10.60.1.5 (in effect you tell VB to create its own network that the host can see)
- from your host, https://10.60.1.1:444 should work
