My modem and/or router are blocking my websites

[Blessings2all]

I have a CM400 High Speed Cable Modem and an AC1200 (R6220) Smart WiFi router and they are blocking me from my own websites that I access on a daily basis. I know that the sites themselves are working because others outside my home can access them and I can access them through my cell phone's internet connection (hotspot). I've checked for firmware updates, rebooted the system and have even done a factory reset. Still not working. How can I fix this?

The release notes walk you through the install

If you hook directly to the modem, do the sites work?

I know you said you checked for updates on the firmware. The automated check doesn't always work. What firmware are you running on it?

Are you using a certain dns provider or the automatic one?

When I connect directly to the modem, the sites DO work.

Router Firmware Version
V1.1.0.34_1.0.1

[Blessings2all]

Automatic

1.1.0.86 is the current firmware. I'd install that manually, factory reset the device, and try without restoring and configuration data. Make sure to install it over a hardwired connection.

How do I install it manually and where is the file?
