I recently bought an OWC 14-Port Thunderbolt Dock (OWCTB3DK14PSG) on ebay. The seller said the dock was in perfectly health and condition (good as new) but I can't seem to get it to power my external monitor or even power a usb keyboard. It does charge my macbook m1 and I'm using certified thunderbolt cables. I even tried updating the driver using parallels but still no luck. Any suggestions?

Lights is blue on dock

laptop shows it's being charged

SD card shows up on desktop when inserted in dock
