freebsd-update: fale?

[Joe Altman]

Greetings, list. I have the following error; though I can load
update5.FreeBSD.org in a browser:

root-is-on-fire # freebsd-update fetch
Looking up update.FreeBSD.org mirrors... 3 mirrors found.
Fetching public key from update4.FreeBSD.org... failed.
Fetching public key from update5.FreeBSD.org... failed.
Fetching public key from update3.FreeBSD.org... failed.
No mirrors remaining, giving up.

Am I missing something in this process?

Regards,

Joe
