Why do I receive the CAS Network Error: Clean Access Server could not establish a secure connection to Clean Access Manager at null. error message?
A. You might receive this error if the Clean Access Manager certificate has expired, cannot be trusted, or cannot be reached. The error is basically due to CAS or CAM communication issues. In order to resolve this issue, verify these items: • Make sure both CAS and CAM are the same version. • If you use a name for the certificate, make sure the name can be resolved using nslookup. • Use the service IP for failover certificate. • Make sure they are time synced before generating certificate. • Make sure shared secrets match. • The Firewall should not ACL block any SSL communication. • Add the CAM certificate as a non-standard root to CAS. • Check for DNS name resolution. • Make sure routing for reachability between the CAM and CAS is correct.
