Hi @JamesTann
re 404 errors on the status updates,
This must be a server issue. Basically the client is getting a “API endpoint not found”. I have never seen this before. I recommend you stick to Hosted Mender until you figure out what the issues on the client side are,
re `mender-auth` reinstall,
Right, the issue is that the identity script (same as inventory scripts) are interpret as configuration files by `dpkg`. We do this so that users can adapt, modify, remove, etc script and still upgrade. To do a reinstall, including conf files, you need to do something like `apt-get purge mener-auth && apt-get install mener-auth`

Hi @lluiscampos,
That worked! I have now restored all the files I need on my physical Ubuntu 22 Server. After that I was able to successfully register with `hosted.mender.io` and deploy an artifact! This is the farthest I have made it so far.
I am now back to where I started with my device, and trying to deploy the update with my own Mender cluster on EKS.
To switch between these two Mender servers I:
1. run `sudo mender-setup` and go through the interactive setup and type in my domain: `mender.mydomain.com`
2. run `sudo systemctl restart mender-authd` and `sudo systemctl restart mender-updated`
Please let me know if this is the right way to switch my device between using Hosted Mender and my own.
I started digging into the Kubernetes logs for both the `mender-deployments` pod and the `mender-api-gateway` pod (are there any others I should dig through?).
`mender-deployments`:
```auto

```
`mender-api-gateway`:

```
These messages appear _without_ a deployment even running. My ingress only has one rule pointing to the Mender API gateway. How can I further debug this on the Mender server side?
I greatly appreciate all the help!

@TheYoctoJester
I am seeing similar issue while using Mender Client v5.0.1 with the community edition mender-server v4.0.1 installed on our EKS.
```auto
{"timestamp":"2025-06-03T18:40:20.784635Z","level":"error","message":"Request to push status data failed: PUT http://127.0.0.1:33467/api/devices/v1/deployments/device/deployments/745b58c7-fa74-4968-b30f-e89cad631a7a/status: "}
{"timestamp":"2025-06-03T18:40:20.784929Z","level":"error","message":"Could not send deployment status: bad version: PUT http://127.0.0.1:33467/api/devices/v1/deployments/device/deployments/745b58c7-fa74-4968-b30f-e89cad631a7a/status: "}
```
Files are getting installed correctly, but since the deployment status update to success is failing all further API calls from mender-update are failing too until the daemon is restarted.
The same client works fine when connected to [hosted.mender.io](http://hosted.mender.io).
On the server side everything appears to be fine and seems to be an issue on the client side. But couldn’t find from the mender client source code what is causing this ‘bad version’ error and which version it is referring to.
Mender client v3(go client) works fine with our server instance, it doesn’t have any problem in updating the deployment status.
