First of all I want to wish everyone a happy and successful new year

I tried to update my OpenEMM 25.04 Instance to 25.11. I was able to update the runtime, though when I restarted the OST I could no longer select "Install or update package from AGNITAS Website" from the Menu because of this error: "Cannot reach: https://www.agnitas.de/download/openemm-version-25.11/"
When I try to open that URL in my browser I get an Error 404.

Could you please provide the required file at that URL?

Thanks and best regards
Mika

Hi Mika, happy new year to you too

The 404 error is expected — the Install or update package from AGNITAS Website option is no longer supported for newer OpenEMM versions. Updates from 25.04 to 25.11 need to be done manually using the official package provided via the OpenEMM download area or GitHub, not through the in-app installer.

I recommend downloading the 25.11 update package directly from the official OpenEMM repository and following the manual upgrade instructions in the documentation. Once applied, restart the OST and the menu issue should no longer be relevant.

Hope this helps!
