freebsd-update metadata error / 12.0-RELEASE-p7

[tech-lists]

Hi,

context: 
# freebsd-version -ku
12.0-RELEASE-p7
12.0-RELEASE-p7

freebsd-update fetch gives the following error:

# freebsd-update fetch
Looking up update.FreeBSD.org mirrors... 2 mirrors found.
Fetching metadata signature for 12.0-RELEASE from update1.freebsd.org...
done.
Fetching metadata index... done.
Fetching 2 metadata files... failed.

How to fix?

thanks,
