CP Server 6.0.5 client fails to communicate with CP Server 7.0 with certificates having 2048-bit keys and SHA256 hashing

Last published : Sep 18, 2026
On Solaris 11x64, if you upgrade a CP Server to 9.0 and accept to upgrade the certificates or configure a new 9.0 CP server, CPS clients on version 6.0.5 or below cannot communicate with the CP Server even after re-establishing trust relationships.

Workaround:

Upgrade the version of the CPS client to 6.1 or later.
