"Host Not Responding" Error with Steam Link on Quest 2?

I installed the new steam link app on my Quest 2 and paired normally to my PC. When I try to connect, however, it says that the host is not responding (Error 200). I can clearly see that SteamVR is running and tracking in desktop VR view on my PC, I can even click and start games, but the headset will not display them. Steam VR still works completely normally if I go through Oculus Air Link, so I'm not sure what the issue could be.
