Kerberos SSO not working for load balancer URL
PeopleTools - 8.58.11
We have a working Kerberos SSO setup in our production environment and same in UAT. Recently our UAT load balancer URL was moved from F5 to AWS and now SSO is failing.
I have tried with individual HTTPS SSO URLs and that works, so the keytab is valid. LB URL throws error - Your User ID and/or Password are invalid.
App server log successful instance (indiv https URL):
