Look like Innuos has pulled the update and provided this explanation on their website:
"07/05/2021: Due to a few rare cases where installing version 1.4.8 caused the Innuos Server to no longer be detected on the network after reboot, we have decided to make the update unavailable until we can determine the exact cause of the issue and prevent it from happening to other users. We will update this page once version 1.4.8 is available again. We apologize in advance for any inconvenience caused."
