ProjectCoordinator Desktop. When I try to log in I see a message saying "Unable to connect. Please try again ", why doesn’t it work?

Most likely, the portal address in "Settings" are incorrect. Check that it says https: // before portal address, and that there is no / after.

If you needed to adjust, save the connection again and try again to click "Connect".
