Cannot run chef-client on chef workstation

I got the following error when try to run chef-client cookbook on the chef workstation.

[root@jasontest chef-client-wrapper]# knife node run_list add ‘recipe[chef-client-wrapper]’
run_list: recipe[chef-client-wrapper]
[root@jasontest chef-client-wrapper]# chef-client
Starting Chef Client, version 13.8.5

Chef encountered an error attempting to load the node data for “

Authentication Error:

Failed to authenticate to the chef server (http 401).

Server Response:

Invalid signature for user or client ‘

Relevant Config Settings:

chef_server_url “
node_name “
client_key “/etc/chef/client.pem”

If these settings are correct, your client_key may be invalid, or
you may have a chef user with the same client name as this node.

Could you have remade this test machine more than once? If so until you delete a node and client from chef it remembers it. If this is the case you can remove the node and client with knife, move the client.pem, and use chef validator to recreate a new client.
