Client too old
Error message
Invalid protocol version (client too old)
Description
During the initial transition from tools that don't check for matching versions to the versions that do check (for example, from 2.4.x to 3.x), you tried to use an old version of the Fusion GUI or command line to connect to a new version of the system manager.
Resolution
Ensure that you are using the same version of Fusion and GEE Server.
