Du kannst ja mal mit
netstat -tulpen
schauen was alles so läuft (…)
Danke dir für den Austausch. Da läuft neben den Docker Ports nur SSH, Apache und MariaDB.
Deswegen hab ich mal Mailcow und Docker gestoppt, dann nftables und ufw deinstalliert:
sudo apt autoremove --purge nftables ufw
… dann Docker und Mailcow wieder gestartet.
Leider ist der Fehler noch immer im Log:
docker compose logs|grep netfilter

Muss ich zur Deinstallation von nftables und ufw noch was tun?
