Bazzite fails to rpm-ostree update

Had Bazzite installed for months now but have not been able to update it correctly for a similar period of time.. Firstly, running rpm-ostree update gives the following error
error: Updating rpm-md repo 'fedora-cisco-openh264-debuginfo': cannot update repo 'fedora-cisco-openh264-debuginfo': Cannot prepare internal mirrorlist: Status code: 404 for https://mirrors.fedoraproject.org/metalink?repo=fedora-cisco-openh264-debug-43&arch=x86_64 (IP: 152.2.23.104); Last error: Status code: 404 for https://mirrors.fedoraproject.org/metalink?repo=fedora-cisco-openh264-debug-43&arch=x86_64 (IP: 35.158.105.37)

Any ideas how to solve please ???
