How to install adds on in HA green - server error

Installation
1

Hi all,
I just started my HA adventure and I bought a HA green to avoid the initial problems with the OA installation.
The system is up and running since 1 week only, and I’ve just done a few things like adding the integration for my Tapo, SwitchBot and Natmo devices, + HACS so I don’t think I messed up something in the code.

I’ve tried to add some add on such as the official File Editor, and the Duck DNS. I have always the same error message

Can’t install homeassistant/aarch64-addon-configurator:5.8.0: 500 Server Error for http+docker://localhost/v1.47/images/create?tag=5.8.0&fromImage=homeassistant%2Faarch64-addon-configurator&platform=linux%2Farm64: Internal Server Error ("unknown:

408 Request Time-out

Your browser didn’t send a complete request in time. ")

error HA

any idea why it happens and how it can be solved?
Thanks

Check your router’s MTU settings. If that doesn’t fix it, check your DNS and other network configuration. Explanation: File editor - installation error
