I am not able to connect to any site with a ipv4 address on port 80 (http) - the connection times out. If I use the secure version of the url (https, port 443) or the site uses an ipv6 address, the connection works as expected. Judging from other questions on the fourm, I may need assistance from @ComcastJohnN.
Try sending him a private forum message;
It may be more effective.
