My hardware was replaced, Core I7-3770 16Gb DDR OMV4 -> Core I3 10100 32Gb DDR OMV5.
And the most important runs again.
It took a while, but now I move more securely in the Docker universe
I still need to do some work on docker network configuration. But other than that, I'm already thinking about what else I can put in containers
Thanks to all for the mental support.
