You need to configure with correct database settings in config.cfg file, database configuration details

I have got the same Problem ... where do i need to setup database ? Do i need to set it up using docker ? Iam stuck at this ...

@n33lix1337 it's your choice how and where you setup your database but database should be reachable from multiav machine.
Also make sure database port is exposed if you are using containers.
