Welcome to the Roku Community, @Mmactavish!
Thanks for reaching out. We'd be happy to share further information about this.
Are you connected to 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 hope you find this information helpful. Feel free to reach out anytime you need help.
Best regards,
Carly
