Hello @Lou Chancrin
It seems from your command that your certificate is SHA-1, but Microsoft adopted only SHA-2 since May 2021:https://techcommunity.microsoft.com/t5/windows-it-pro-blog/microsoft-to-use-sha-2-exclusively-starting-may-9-2021/ba-p/2261924
I would suggest talking to your certificate provider, in many cases the provider may reissue the certificate to meet the current requirements.
Hope this helps with your query,
