Can No Longer Access a Single Web Server (Worked and then all of sudden could no longer access)

@EGI am having the same issue as this right now.  There is only 1 sight I can't get to, everything else works.  I can get to the site if I connect my computer to my phone hotspot and everything works fine.  Connect back to the Xfinity router, can't get to it.  When I do a traceroute it stops at the Xfinity router.  It is like there a a firewall rule at the router blocking the route from my Xfinity router to the website.  The IP I am trying to get to is an ISP I use where I have multiple web sites running.  It was working fine yesterday and then all of a sudden I lost connectivity and can no longer get it.  I spoke to ISP support, IP is cleared from any list of being blocked.

I can't see anything on the Xfinity router about blocking the route from my Xfinity IP to my web server IP.

I found the issue and resolution.  The xfinity router had the Advance Security feature turned on and it was there that it made the determination that it was a threat and blocked the IP.  I turned the Advance Security off and then back on and then was able to access the site.  Here is a link to describe how to turn on and off.  In short

App on phone (Although when I tried, I received an error when trying access the page.  I used the web site)

  • Connect tab, selecting the Advanced Security tile and following the steps to turn it on.
  • You can turn off Advanced Security in the Xfinity app by selecting the Person icon The person icon appears as a stylized head and shoulders inside a circle. in the top-left corner of the app, which will bring you to the Account page. Then, scroll down to More Resources and select xFi Advanced Security.
  • Select Turn Off to toggle Advanced Security off.

Web Site

  • To disable Advanced Security through the xFi website, select More > My Services > Turn Off.

That's fine for an individual. I advise that all the time.  But it's not practical or feasible for site owners to tell everyone of their customers and potential customers on the internet that are using those gateway devices to do so.
