I read that this is some error about the iptable configuration and that docker blocks it and i tried some solution like switching to legacy iptables but then the setup didnt even start and docker has errors.
Had has someone else this problem and any working solutions for his setup? I would really appreciate help with this topic.
Thanks and best regards
