@jsing You may well be correct that the server was incorrectly configured, unfortunately it was a Windows server managed by a third party and I don't know precisely how it was set up. Given that the cert in question was issued on 9th September 2021 I suspect it was a misconfiguration of their intermediate cert they were sending.
