TP-Link Kasa EP40A & EP25 won't connect

So I’m brand new to Homey and have had success adding many of my existing home devices but for some reason the TP-Link Kasa app is just not having it. I log in with my Kasa account, I get a message from Homey saying I’m logged in and can close the window, and then I’m told that no new devices have been found. Over and over again. Has anyone run into this?

Do you use a separate network for your smart devices?
