According to the [docs](https://docs.ansible.com/ansible/latest/reference_appendices/faq.html#how-do-i-configure-a-jump-host-to-access-servers-that-i-have-no-direct-access-to) setting _ **ProxyCommand** _ in _ansible\_ssh\_command\_args_ will enable access to private servers via a jump server.

I am attempting to do this but keeping the error **_Control socket “/Users/pnotes/.ansible/cp/cfed83541a” does not exist._**

My current setup is thus:

ansible/test/inventory.ini  
`[all]`  
`bastion-0`  
`private-server0`

`[bastions]`  
`bastion-0 ansible_host=104.xxx.xx.xxx`

`[private_servers]`  
`private-server0 ansible_host=68.xxx.xxx.xxx`

ansible/test/host\_vars/private-server0.yaml  
`---`  
`ansible_ssh_common_args: '-o ProxyCommand="ssh -o StrictHostKeyChecking=no -W %h:%p -q root@bastion-ip-address"'`

the output of running playbook command with -vvvv:

I don’t understand why this isn’t working and would greatly appreciate an explanation. Thank you.

**Note:**  
When I edit my personal ssh config file (~/.ssh/config) with the details of the jump server and the private server, I am able to connect without a problem. BUT I would rather not have to edit my personal ssh config file for ansible controlled hosts (these are setup/torn-down numerous times for testing, staging environments).
