This failure started only after the IdP upgrade, CAS version remain as is,
and no other change except IdP version upgrade,

I was able to see the CAS service validate URL has been changed to 3.0
protocoal https://<CAS HOST>/cas/p3/serviceValidate in the call from IdP to

With previous IdP version 3.3.x it was CAS2.0 protocol with URL https://<CAS
HOST>/cas/serviceValidate   and it worked without issues

So in the new IdP version I added below config in the idp.properties
assuming it will work as it is CAS20 but still it failed with the same ERROR

shibcas.ticketValidatorName  =  cas20
