Suse 15 Repository not working

[sdkun3456]

Hello,
I want to run this two commands:
zypper addrepo https://repo.linuxfabrik.ch/monitoring-plugins/sle/linuxfabrik-monitoring-plugins-release.repo
zypper install linuxfabrik-monitoring-plugins

The Repo will be added, but it seems not to be a valid Suse Repository. This happens after runnig "zypper ref":
Retrieving repository 'Linuxfabrik Monitoring Plugins (release)' metadata .........................[error]
Repository 'Linuxfabrik Monitoring Plugins (release)' is invalid.
[linuxfabrik-monitoring-plugins-release|https://repo.linuxfabrik.ch/monitoring-plugins/sle/15/release/] Failed to retrieve new repository metadata.
History:

• [linuxfabrik-monitoring-plugins-release|https://repo.linuxfabrik.ch/monitoring-plugins/sle/15/release/] Repository type can't be determined.
  Please check if the URIs defined for this repository are pointing to a valid repository.
  Skipping repository 'Linuxfabrik Monitoring Plugins (release)' because of the above error.

The SUSE packages are not yet available, they are planned to be published with the next release. Regrettably, we cannot provide a specific release date as of now.

As an alternative, the monitoring plugins can be installed using the “zip” and “source code” installation methods as described in https://github.com/Linuxfabrik/monitoring-plugins/blob/main/INSTALL.md
