Non intercepted is not bypassed… Squid has coupe options for the “http_port” option. One that you are using is intercept and the other is without intercept. What happens when you try to connect to this website when you are defining another port without “Intercept” and define the proxy in the browser settings? Let me know if something is missing in the picture.

Once the site IP is on the bypass list, it opened without an issue. There are a few other .http://gov.co sites who have the same problem too.
