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.
