LDAP connector is reporting "certificate has expired"

Help
,
1

I am installing the LDAP connector on a test server
this is on Windows Server 2022 running Active Directory domain services
I have installed a Let’s Encrypt certificate today that is set to expire in 3 months
when I open the localhost configuration page for the AD LDAP Connector v6.1.8 Configuration and enter the Ticket URL, the page reports to me:
“Network error: certificate has expired”

Since the certificate that I am attempting to use was just issued today and indicates that it is good for 3 months, is there some other certificate that is expired?
