Please post the output of a traceroute to the site. It may reveal where the blockage is.

Hello,

I am having issues where I can only access certain sites (google, maps, youtube, etc.) but not others (amazon, coinbase, etc.).  Not sure if its a IPV4/IPV6 issues but I'm guessing it is.  I've tried resetting the gateway, hard resetting it, changing my DNS to google public.  Nothing works.  Any help would be much appreciated!

Has there been any resolution that you’re aware of? I have several websites and I’m not able to access also with my Comcast router and nobody seems to know how to fix it and they act like I’m the only one in the world that has this problem!

That's why we ask people to perform a Ping or a Traceroute to the affected sites to see if the problem is on your home network, on Comcast's infrastructure, or the hosting site. 

If you don't know how, review the instructions in Xfinity Internet Connection Troubleshooting Tips.
