This error prevents me from watching content on my PC. Why? I'm a paying customer.

What app are you using/watching?
Start by trying a "System restart" under Settings->System or Settings->System->Power depending on your Roku device.
Edit: Sorry, totally missed that you're watching on a PC.
If you are trying to watch the online Roku Channel, https://therokuchannel.roku.com/, verify that you are not using a VPN or proxy server. That particular/similar message language will trigger when a VPN is detected/suspected.
I tried watching from the Roku Channel on their website using Google Chrome, version 109.0.5414.168.
I tried watching a movie titled, "The Grey" and received the error. Then I tried random other movies and live streaming TV and received the same error. Could not watch anything. I use no VPN. If there is anything upstream of my Spectrum internet service that may interfere, I know nothing about it.
Amazon Prime no longer supports my outdated version of Chrome on Windows 8.1. I told them that they are not improving they are not making any friends with that move.
Sorry, I forgot to mention, I can watch content on my TV with Roku dongle just fine.
If Chrome cannot be updated on your computer, try using a different browser like Brave or Firefox. Make sure to go into the Settings for the browser after installed and enable DRM. (most browsers have DRM disabled by default).

I don't use Windows, but I do have browser projects that rely on older Chromium builds and they are not compatible with the online Roku Channel. (may be a similar situation that you are running into). I generally just use Brave when I am viewing Roku Channel online.

Edited to add... another forum where this issue w/chrome v.109 and win8/10 seem to be affected 11/2024. Couple of technical workarounds posted there, but general consensus was to just switch to another web browser.

Most likely your outdated browser and Windows OS is causing the issue. Maybe you can download a different browser that may work.
