I have a different adapter (based on FTDI FT232RL) and my serial console works reliably.
My connections:
Adapter Rock64 (Pi-2 Bus)
GND <---> pin 6 GND
RXD <---> pin 8 GPIO2_A0 (UART2_TX_M1)
TXD <---> pin 10 GPIO2_A1 (UART2_RX_M1)
Are your connections the same?
If yes, I would start with replacing wires between adapter and Rock64.
I would also replace USB cable between adapter and workstation.
Also it's very important that you keep your adapter set at 3.3V (I think pin 10 on Pi-2 Bus is connected directly to the RK3328 chip).
