problem description

I locally use Wechat to test the official account and run a PHP project. The page is authorized here, and the following page appears, but clicking to confirm login has no effect, and there is no response. Some people say that it is the resolution, font size and other problems. I am the pro of Xiaomi notebook. The default font is 125%. Changing it to 100 is still invalid.
in addition, why is there such a request url: https://open.weixin.qq.com/0 in my request? How did this wrong url come into being? I am a new developer of Wechat, please help me, thank you!
