xcrun can't download tools

I'm trying to test the new noterization tool, but when I execute xcrun from the Terminal it says it needs to install the command tools. I agree, but then immediately get a dialog that says:


"Can't download the software because of a network problem"


I've got a hard-wired Internet connection, the same one I used to download the Xcode beta, and everything else Internet releated appears to be working just fine. However, I will point out that I've also been unable to get any Mojave updates to work, as I get a similar error that there was a "download problem."


So at this point I'm stumped.


Any suggestions?
