Using Ansible to run nuclei commands

We have an issue with backup snapshots getting stuck on our cluster, and of the many ways we use to find these, one of them is running the command:nuclei vm_recovery_point.listI was hoping to start down the path of automating the discovery of these recovery points using Ansible.  However when we run the nuclei command via Ansible, we get this error:            "E0724 14:10:07.661153Z   15562 jwt.go:82] ZK session is nil",            "2023/07/24 10:10:07 Failed to connect to the server: websocket.Dial ws://127.0.0.1:9444/icli: bad status: 403"I think this means that nuclei calls the localhost websocket on the CVM, but Ansible interprets that as a call to the server I’m running ansible from (ie the ‘controller’ server), and not the CVM I’m remotely connected to.Does anyone have any advice on how to handle this?  I’ve also looked at API calls, but can’t find any that give me the same info.

Missing disks in Prism Element

Greetings,In the Prism Element web console under the Hardware menu, there are drives on one of our nodes that are not showing up under the Diagram, but are showing under the Disk screen from the Table menu (see below).   As you can see, all disks are all online and confirmed via the CLI as well.  Our Nutanix versions are below.  I’ve restarted the Prism service for this node and still showed the same result.Any help would be appreciated. Thank you,

Protection Domain Based DR

Hi, I am having two physical sites with on-prem nutanix cluster. I am trying to config async dr from primary to secondary site every one hour. So the snapshot will trigger every one hour and replicate to the secondary site. I read in the portal , the first replica is a full copy and the subsequent are incremental. My question here is , once my first replica, which is a full copy of my data was completed to the secondary site and certain period of time, my first replica will expire and deleted based on my retention configuration. In that case, how can I restore my full data with the help of incremental snapshot from the remote site?

Upstream connection error: reset due to connection failure before headers

Hey guys, newbie to the forum here. I recently setup a ce version of Nutanix in our work lab environment on vsphere. Up until last week I was able to log into the gui, I can still login via putty.When I try to log into the gui now, via xxx.xxx.xxx.xxx:9440/console/#login - I get the above message.I have also had the message "server is not reachable”I did think about trying the install again but thought I would ask the question first and see if anyone else has had the same problem and if so how they got around it?  Thanks in advance.
