In:
https://dl.fedoraproject.org/pub/alt/screenshots/f44/
(and other Fedora versions) in the files:
- failed.html
- matrix.html
- status.html
there are URLs of type:
https://apps.fedoraproject.org/packages/${NAME}

Opening them you get redirected to:
https://packages.fedoraproject.org///${NAME}
which prints error 404. You can manually fix it to:
https://packages.fedoraproject.org/pkgs/${NAME}

$NAME can be "90-Second-Portraits".
I do not know if this is the correct package, and if it must be fixed in the HTML file creation and/or in the URL redirection part.

Reproducible: Always
