Help with cabal

I'm setting up my GHC builds on a new machine, and this time I'm using WSL (windows subsystem for Linux).

Small problem.  I've installed cabal-3.0, and say "cabal update".  But I get

Unexpected response 502for

And indeed, that's what a web browser says for that same URL.

What do to?

Oddly, on another also-new Windows machine, I do exactly the same thing, and with 'cabal update -v' I can see that it gets the same error, but then moves on to try, which works.

Why does the behaviour differ?  And, at least for now, how can I get the first machine to look at
