I used to connect both through Wifi, and it worked like a charm, but the Wifi was unstable on the Mac Mini. Now I connected the Mac Mini through ethernet but cannot combine both through Universal Control. Is there a way to achieve this?

I can't find a definitive 'Ethernet is not allowed' but Apple does say Bluetooth & WiFi 'must be on'.
Apple KB - Universal Control: Use a single keyboard and mouse between Mac and iPad
It's quite possible to have simultaneous Ethernet & Wifi connections, just set Ethernet to be the Primary, in Network > Advanced…
