OpenStreetMap not showing

Hi, I’m in TM 2024.1.2. The parts of TM that use OpenStreetMap aren’t working - setting the project Location and the Populate Urban both just show the map as a blank rectangle. Typing into the search box seems to generate suggestions but no guarantee that I’m selecting the right location.

I’ve tried restarting TM, signing out and in of my account, etc. Our IT guy seems to think it’s an external issue. Anyone else having problems with it?
