Failed to retrieve new repository metadata from http://mr.heru.id (OpenSUSE Tumbleweed Non OSS)

I tried to update my OpenSUSE Tumbleweed on 4 June 2025, but when I ran sudo zypper up, this message showed up:

`Retrieving repository 'Main Repository (NON-OSS)' metadata .............................................................................................................................[error]
Repository 'Main Repository (NON-OSS)' is invalid.
[download.opensuse.org-non-oss|http://download.opensuse.org/tumbleweed/repo/non-oss/] Failed to retrieve new repository metadata.

  Please check if the URIs defined for this repository are pointing to a valid repository.
  Skipping repository 'Main Repository (NON-OSS)' because of the above error.`

This error is only found in the Non-OSS repo, there is no issue in any other repos.

Start by checking the MirrorCache redirect for the non-OSS repository URL and whether the referenced metadata is available through the selected mirror, using the reported zypper error as the reproduction. Compare this repository with the other working repositories. Done means the non-OSS repository metadata can be retrieved successfully without the reported missing-file error.
