Firewall rule id:0 : Economist (Eiu.com) site blocked

Question

New to SophosX and not a network Pro. but can tinker and go deep as needed. Using it to secure my home network. 
 
 My sophos rules are the default rules. did not do anything specific. There is a default rule allowing all LAN to WAN traffic and hence expect, that part should work well for all. 
 Tried accessing the site pages.eiu.com (Economist site). dropped pack due to the Firewall Rule iD:0 in the policy tester. Cant figure out a way of allowing this. Do i need any other explicit rule? Wont my default rule, supposed to handle this? 
 
 Any help is appreciated. 
 
 Thanks

Finally boiled down to the root cause. 
 
 For DNS of Https (Cloudflared or equivalent to work on all sites) in pihole, This is what i did 
 1. my Cloudflare based DOH was running in port 5053 in Pihole 
 2. So created a new service called DNSoH and added protocal/source/dest ports for 53, 5053 and 443 (combinations and permutations of these ports) as follows 
 
 TCP (53) / (5053), TCP (5053) / (443), TCP (5053) / (53), TCP (53) / (443), UDP (53) / (5053), UDP (5053) / (443), UDP (5053) / (53), UDP (54) / (443) 
 
 3. That solved the problem. Most of rule:0 exception is gone
