Advanced Security is blocking access to websites, then does not report that it's blocking the access

Xfinity should provide a way to correct this. Otherwise, Advanced Security is kind of useless.


My home network can't get to
... a reputable astronomical equipment site, unless I turn off Advanced Security. Comes back unreachable in "ping" and 'no response' in chrome. I have had the same issue with other random websites.


Advanced security is supposed to tell me when it's blocking activity. I get random notices of some home devices that AS supposedly blocked, but it does not report when it's blocking websites I'm trying to reach. Why not?


If I sign into our xfinity home gateway at as admin, I can ping and tracert which is at , (address apparently actually belongs to "") from gateway "diagnostic tools":
Status: Complete !
1: 8,7,8
2: 8,9,8
3: 12,12,11
4: 11
5: 13,14,14
6: 13,14,13
7: 30,17,13
8: 14


BUT, advanced security blocks that address from getting through to our home network.


from my PC, "nslookup" returns the correct IP, but its "unreachable" if I try to ping, tracert, or try to access through a browser: 


This is what I get:

Address: 2001:558:feed::1
