Steam Link App on my Chromebook Can't Find Any Computers to Stream From

[philiphalabi35]

I installed the Steam Link app on my Chromebook. It's an Acer Chromebook 15 CB5-571. It has Android 7.1.1 and the Google Play Store also. When I run the app, it says it can't find any computers. I have a Windows 10 PC that has Steam installed on it. It was turned on and I was logged into my Steam account, but the app didn't recognize it. I read online that I could try typing in the IP address from my PC. That didn't work either. I'm logged in to the same Wifi network as my PC. What should I do? Here are the specs:
