Some package mirrors are returning permission denied

[Creaky]

Hi,
Trying to upgrade a FreeBSD 14.3 system ports. Worked yesterday, failed today.
Other FreeBSD systems in different locations around the world are working correctly.

Is this a transient issue or are some mirrors broken?

Failures are using pkg0.syd.freebsd.org
Successes are using pkg0.nyi.FreeBSD.org
Determined by fetch "https://pkg.freebsd.org" and reading the content.

Example failed pkg update run

Unable to update repository FreeBSD

Error updating repositories!

The FreeBSD.conf file is

FreeBSD: {
url: "pkg+https://pkg.FreeBSD.org/${ABI}/latest",
mirror_type: "srv",
signature_type: "fingerprints",
fingerprints: "/usr/share/keys/pkg",
enabled: yes
}
FreeBSD-kmods: {
url: "pkg+https://pkg.FreeBSD.org/${ABI}/kmods_latest_${VERSION_MINOR}",
mirror_type: "srv",
signature_type: "fingerprints",
fingerprints: "/usr/share/keys/pkg",
enabled: yes
}

Changing the site to the working mirror fails due to HTTPS SSL peer certificate naming mismatch.
Only got an update through by dropping pkg+https and using just HTTP.
Obviously that is not desirable.

Any thoughts or possible solution?
