Hi Lucy,
-I'm not sure where Channels is.
-I don't have another hotspot for both.
-I'm on Windows 10.
Answering the questions incase someone else searches with this problem. I was able to fix it, I restarted my PC and got a windows pop up that Windows Firewall blocked Skybox from accessing private and public network and had a checkbox if I wanted to allow. I checked it previously for private and left public unchecked since I just wanted the private network to work but doing this didn't fix it.
So I uninstalled and reinstalled Skybox and it gave this pop up again after restarting and launching it. I this time clicked to allow on private and public network, checking both and it works now. Windows 10 desktop autoblocked it on both by default but didn't let me modify until I restarted it and gave me a warning popup that it blocked it and if I wanted to allow it.
