Hi all,

Ive been trying to introduce hop nodes and other ee’s into my cluster but I cant seem to get my inventory correct. When I run the setup.sh it fails on the receptor mesh calculation saying

" TASK [ansible.automation\_platform\_installer.receptor : Calculate Mesh Topology] \*\*\*

**task path: /opt/ansible-automation-platform/bundle/ansible-automation-platform-setup-bundle-2.5-17-x86\_64/collections/ansible\_collections/ansible/automation\_platform\_installer/roles/receptor/tasks/calculate\_mesh.yml:2**

fatal: [[controller.example.net](http://controller.example.net)]: FAILED! =\> {

“msg”: “There are receptor nodes that do not have a path back to the control plane: [ee01.example.net](http://ee01.example.net), [ee02.example.net](http://ee02.example.net), [ee03.example.net](http://ee03.example.net)”

Here is part of my inventory file.  
FW’s are open between the controller, hop nodes and ee nodes so there should be an open path back to the controller which its saying there is not.

```auto
[automationcontroller]
controller.example.net

[execution_nodes]
ee01.example.net receptor_peers=controller.example.net
ee02.example.net receptor_peers=hn01.example.net
ee03.example.net receptor_peers=hn02.example.net

[hop_nodes]
hn01.example.net receptor_peers=ee01.example.net,controller.example.net mesh_server=true
hn02.example.net receptor_peers=ee02.example.net,controller.example.net mesh_server=true

```

Not sure what Im missing in my above inventory to make this work.  
Thanks

Never mind i was able to figure out the correct syntax in my inventory file to get this to work.
