Well............
On further examination, we are not on the latest version of the CredentialsBinding plugin.
We are at CredentialsBinding v 1.16 while 1.20 is out....
Also we do not have the current dependencies of Credentials Plugin v 1.20 either...so we are behind which is probably while the CredentialsBindingPlugin is not working with certificates
Pls see
T^hank You
SIGH .......
