Google Home Mini and Google Assistant

I have a Google Home Mini and a Bose 300 with Google Assistant connected through Wi-Fi to my Xfinity Router.  Up until 6 months ago or so, we had never had any issues with saying "Hey Google..." and it would respond.  Now it takes 3-4 times of asking before it does the action requested.  Each time it does not, it replies "Hmmm, something went wrong, try again in a moment" or something like that.

I have restarted my network, reset each device, reinstalled the devices on my network, reset my Google account and assigned to new google account and nothing works.  I have been told from a few that it may be the Firewall of IPV4 or IPV6, but not had luck when one is disabled and then someone mentioned ICMP Packets which I have not figured out how to find.

Anyone else with this issue and found a solution.  This is very frustrating for certain.
