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
www.optcorp.com
... 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 10.0.0.1 as admin, I can ping and tracert optcorp.com which is at 23.227.38.32 , (address apparently actually belongs to "myshopify.com") from gateway "diagnostic tools":
Tracert:
Status: Complete !
1: 8,7,8 96.120.106.113 96.120.106.113
2: 8,9,8 24.124.179.209 24.124.179.209
3: 12,12,11 96.110.92.17 96.110.92.17
4: 11 96.110.235.17 96.110.235.17
5: 13,14,14 be-31431-cs03.ashburn.va.ibone.comcast.net 96.110.40.25
6: 13,14,13 be-2204-pe04.ashburn.va.ibone.comcast.net 96.110.37.134
7: 30,17,13 as2906-c-3.sanjose.ibone.comcast.net 173.167.57.102
8: 14 myshopify.com 23.227.38.32

 

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:

C:\Users\smatt>nslookup optcorp.com
Server: cdns01.comcast.net

Non-authoritative answer:
