SketchUp 2018 - Getting an Error Message Connecting into 3D Warehouse

I’m in SketchUp Pro 2018 and trying to open 3D Warehouse and getting the above error message. This is the first time I’ve see this. Normally I have no trouble getting into 3D Warehouse. Has SketchUp dropped support on SketchUp 2018 Pro as it relates to using 3D Warehouse? I checked my internet connection and I have a connection as I can get to this forum.

I did see this for the first time recently. We’re investigating related things, hopefully something obvious will show up as the cause.

In the meantime, for me I could connect to Extension Warehouse, and after that 3D Warehouse was ok.
