Why is my device polling localhost?

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:

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!
