ssl certificate verify failed

With the development of the Internet, it has been deeply in all aspects of people's lives, it can be said that we are inseparable from the Internet. In the face of human dependence, Internet security is increasingly important, personal privacy is increasingly needed to protect. How can we improve the security of our Internet access? How to protect the privacy of our internet? How to prevent being hijacked by hackers? And so on, many security factors need to be taken into account.HTTPS has gradua
