Vivado can't open PYNQ-Z1 as hardware target

I’m following a beginner tutorial here and have completed all steps successfully until 10:55 in the video, when I try to actually load and run the bitstream on my pynq-z1 (Open Hardware Manager → Open Target).

The board is connected by ethernet and running a program that was on the SD card/image I originally set it up with (LEDs 0-3 are on). From my host machine, I can ssh into the pynq via the IP.

What might I be doing wrong? How can I directly inform Vivado of the pynq’s IP address?
