After the update of the on-premises deployment, this error appears. What could be the root cause?

Hello @GiorgioS13

Could you please share when do you receive this error message, is it while accessing Kibana ?

As per the error message this seems to be related to “maintenance windows”

Can check Kibana Logs in order to understand more about the error.

What was your older version & current version of ELK ?

Thanks!!

Hello @Tortoise

Thank you for reply.

I noticed this issue when navigating to **Security \> Alerts**.

The message states:  
**“Maintenance windows are a subscription feature.”**

I do not have a subscription license.

The current version in use is **9.3.0**.

Hi all,

We’re have the same error message on our 9.3.0 stack after upgrading from 9.2.4. Only shows up on the Security pages and Synthetics pages.

We also don’t have a subscription so accessing the Maintenance Window page simply asks if we’d like to trial or upgrade.

```auto
fetchResponse@https://{hostname}/30ab63cc0017/bundles/core/core.entry.js:1:244583

```

It’s not harming anything - but is annoying when it pops up over a button I’m about to click lol

There’s no related error message in the Kibana or Elastic logs - the closest message is this:

```auto
kbnode1 | [2026-02-11T11:48:40.643+00:00][ERROR][plugins.fleet.fleet:agent-status-change-task:1.0.2] [AgentStatusChangeTask] error: ResponseError: search_phase_execution_exception
kbnode1 | Root causes:
kbnode1 | script_exception: runtime error

```

But I have a feeling that might be completely unrelated?

Many thanks!

This seems to be a bug, have you reported it on Github already?

You should report there.

As far as I have observed, it does not break anything and does not seem to have any impact however, I am still interested in understanding the root cause.

Wow good shout, didn’t even check there.

There’s already a bug for it from December 2025
