Urgently want to know why yao network status, check not a local address, enter localhost: 8080, return to check the result is a line of red, status display does not return information, as shown in figure 1, but when I in local browser can login this system? As shown in figure 2, the great god are glad to help children

The second question is, can't understand when input url rules, such as check the baidu, enter www.baidu.com can, but not a https://www.baidu.com (check only one line), as shown in figure 3
Check Tmall but, instead, is to enter https://www.tmall.com, if the input www.tmall.com, the results will be only one line of http://www.tmall.com test results, as shown in figure 4,
So, is also the HTTPS protocol address, why can't some to enter some input, what is inside this immortal law ducks feed
