Could you please confirm if you have installed the AppDynamics package on the same server OR copied it from some other server? If copied, could you please remove the agent files and install it on the target server and try? We have some native dependency on the underlying OS and architecture which may cause the issue and hence we recommend to install the agent via npm on the server itself.


Best Regards,
