I ran into the following error while trying to get Netflix running on the Chrome OS with the Chromium browser. The error was some variant of: C7121-1331-P5 (I also got C7121-1331-P7). Netflix was unable to solve the problem. After checking it out, I found that it had to do with widevine and I then found this rather elegant solution from Neverware (which was the underlying software that I was running). Hopefully this will streamline the process for someone else!
