Looks like the Apple servers glitched, or your network connection to Apple glitched, or maybe there’s a first-few-hops VPN involved and that glitched.

HTTP 401 is “forbidden”, so I’d also check your login and token, and check whether (for instance) there’s another Apple Developer agreement waiting for your approval at the portal.

If you’ve restarted and checked your traceroute to that Apple host and have no VPN installed, and it doesn’t resolve in an hour or three, and it’s not a problem with your login and your agreements at the portal, contact Apple Developer Support.

If it persists, and if the operation is executing on GitHub, you might want to contact Apple Developer Support anyway, and ask whether that’s a factor; whether Apple is checking IP submission addresses and blocking some.
