Is that a mirror issue? The URL itself is valid.

Error messages should be improved. These sources are not in our source mirror. The packages all recent upgrade it seems. There are 2 downloads directories and rsync to syncrhonize them. Take one URL that fails and see if it's working on downloads.yoctoproject.org.
FYI, I've checked, mirror URL looks fine now: https://git.yoctoproject.org/poky/tree/meta/recipes-graphics/mesa/mesa.inc: SRC_URI = "https://archive.mesa3d.org/mesa-${PV}.tar.xz \ ... SRC_URI[sha256sum] = "b1c45888969ee5df997e2542654f735ab1b772924b442f3016d2293414c99c14" $ wget https://downloads.yoctoproject.org/mirror/sources/mesa-25.1.0.tar.xz $ sha256sum mesa-25.1.0.tar.xz b1c45888969ee5df997e2542654f735ab1b772924b442f3016d2293414c99c14 mesa-25.1.0.tar.xz => The recipe sha256 and the downloaded sha256 match
We have an open bug to track improving the error message. This issue hasn't been seen in a week or so.
