Welcome to the Roku Community, @Edgar3.
We appreciate you reaching out for support. Rest assured that we'll help you stream Live TV channels on your Roku.
Before we proceed, could you please let us know where you are currently located? Your device is currently connected to a USA network, but could you please confirm if this is a VPN?
If so, please be advised that it can cause playback issues or no playback at all. Content providers continue to update their security measures to prevent unauthorized viewing, and it's possible a change was made that prevents your VPN from working.
This is by design and intended, but using your standard ISP without the VPN will be the solution here.
We will be able to assist you further with more detailed information. We anticipate your response.
Best regards,
Carly
