Windows 10 19035 upgrade has broken DVR

Today I upgraded to Windows 10 19035 and it seems that DVR can no longer find my HDHR, nor can it access TV Everywhere (PS Vue). When I looked at the settings the HDHR is just gone. Manually entering the IP address has no result, and no log output is shown for the attempt.

I can still connect from clients and stream previously recorded videos.

OS Windows Microsoft Windows 10 Pro 10.0.19035 Build 19035

The log is filled with TVE errors:

Also live TV works from my clients, but not from the Channels DVR web application on the PC.

This is a firewall issue. Connections from the dvr are being rejected, so it can't access your HDHR or the internet

After digging some more, it looks like Norton was blocking some DVR functions. Some tinkering has restored operations.
