    @Thomas,

    unfortunately not yet, I could not duplicate the issue on a local site then not able to debug for its main root cause.

    Although I think this issue relates to the another https://our.umbraco.com/packages/website-utilities/seo-checker/using-seochecker/99363-seochecker-error-running-scheduled-task
