Hi there.

It’s come to my attention that Comcast’s man-in-the-middle “Advanced Security” attack has been enabled by default for a large majority of their customers, and as such has blocked connections to files.catbox.moe.

You will need to disable their MITM attack by following the instructions here (obviously disable instead of enable): https://www.xfinity.com/support/articles/using-xfinity-xfi-advanced-security 

Thanks,
