Problem after playing with my networksettings in OMV 6 *urgent*

Hi I use some Docker Images in my OMV installation. I use Portainer to deploy them.

Now i've seen veth interfaces and thought i can bind them to any IP.

I figured out which docker container has which veth and was setting my veth for my Nextcloud Docker to static IP: 192.168.178.200 SUB: 255.255.255.0 DNS/Gateway: 192.168.178.1

After applying these settings, my OMV is no longer accessible.

How can i revert this? Is there a config file where i can delete some entries?

Didn't work, but i found a solution.
