Firewall Blocking Random Sites

Hi, I am using Comodo Firewall 10.0.1.6294, Windows 10 and doesn’t have any other active security programs running. My firewall is switched to Custom Ruleset and have turned OFF all Advanced settings. I have tried on both Firefox and Microsoft Edge and both I can’t access some websites such as Amazon.com, taobao.com but I have no problem accessing other websites. As soon as I turn OFF the firewall, these websites load instantly.

Anyone have any idea whats wrong?
