Invalid Certificate - All Course Videos - OS X Sierra Beta 10.12.1

I can’t play any of the course videos with the latest OS X beta - 10.12.1

I’m getting the following error:

[Error] Failed to load resource: The certificate for this server is invalid. You might be connecting to a server that is pretending to be “skyfire.vimeocdn.com” which could put your confidential information at risk. (master.m3u8, line 0)

If I bring up the web inspector and select the failed link, it says the certificate has an invalid issuer.

Anyone else seeing this error?

Hi @motivdev

Sorry you’re seeing this. I suspect this might be a change in the root certificates bundled as part of macOS in the beta of 10.12.1 you’re using.

In order to determine whether it’s a problem with macOS or with our video host (vimeo) I need some more info on the certificate error. Are you able to screenshot the details of the rejected certificate?

thanks
