Marketplace unavailable from within Cura?

[pnt103 0]

When I click on Marketplace in Cura, I get an almost-blank window stating "Could not connect to the Cura package database. Please check your connection."  The PC is running a fairly new install of Windows 10 Pro.  I've tried installs of 4.9.0 and 4.10.0, both with my old profiles and clean installs (having removed all files myself), both with and wthout logging in to Ultimaker, etc.  Finally I tried on my old PC (also Windows 10 Pro) which was working fine a week or two ago: same problem.  Nothing on our network has changed.  Is this related to the issue with Let's Encrypt SSL certificates noted at http://status.ultimaker.com/ ?

Yes. It seems that not all windows machines got the new certificates (https://twitter.com/hmoffatt/status/1443848907893592072). It worked on my own windows machine after i installed the pending updates, but i'm not entirely sure that was it, since one of my colleagues has an up to date windows where it didn't work.
