   1. Ensure SSH access works: ssh $ACTUAL_USER@$CORE_SERVER_IP
   2. Verify core server has: /opt/stacks/core/shared-ca/ca.pem
   3. Manually copy CA: scp $ACTUAL_USER@$CORE_SERVER_IP:/opt/stacks/core/shared-ca/ca.pem $ca_dir/
   4. Regenerate server certificates on this server with shared CA
   5. Restart Docker: sudo systemctl restart docker
   6. Test connection: docker --tlsverify --tlscacert=$ca_dir/ca.pem --tlscert=$ca_dir/cert.pem --tlskey=$ca_dir/key.pem --host=tcp://localhost:2376 ps
