okay, I thought to have solved the problem but I was wrong, here I go again. When I docker compose up -d the immich server (the only one I have installed) all those routes are created, and apparently some of them conflicts with something else and now my host has no internet connection. however it seems that ip route flush 0/0 solves the problem until the reboot, which is strange. the other command returns RTNETLINK answers: File exists
