The management server of Advanced Threat Protection (ATP) Virtual Edition (VE) fails to serve a user interface (UI) after the ESXi host where ATP VE is deployed loses connection to its remote datastore.
Instead of reaching the user interface, the client browser will search the internet or display "
Unable to connect".
If support is contacted while ATP has its /tmp partition in read-only mode, and before the machine is restarted, support can find messages similar to the following in /var/log/dmesg:

To repair the corruption caused by the ESXi Host losing contact with its datastore, please re-install ATP from OVA.
