Unexpected exception occurred while processing REST request. org.eclipse.jetty.io.EofException: null

I’m seeing this regularly in my log. Everything seems to working, but I wonder what is happening.

Running openHAB 3.2 Release on a Pi 4B using openhabian.

This looks like a duplicate of this topic, which has to do with the iOS app for Openhab somehow causing these error:

https://community.openhab.org/t/oh3-problem-with-writing-the-data-class-org-openhab-core-io-rest-sitemap-internal-pagedto/111255

Same problem here, but not using IOS but Android app.

Looks like I experience the same. My error is BTW preceded by a warning:

Hi all,
I have a similar issue, error messages when I start openhab app on IOS or when I click something within the app. I found out that this error only happens, when my VPN is started on my iPad. Shutting down the VPN and restart Openhab app does not end up in any failures.
Do you also have VPN running?
