https exception refers to https certificate exception. In fact, there is an error in the https certificate and it cannot be used normally.
So what causes the https certificate to go wrong?
The reasons for https certificate exceptions (errors) can be summarized into three points:
1. There is a problem with the https certificate itself. There are many https certificate issuing authorities (CA) on the market, but few are reliable. If you choose to deploy an https certificate issued by an irregular CA organization to the website, then the https certificate will be abnormal and cannot be used. It plays a protective role, because the https certificate issued by this organization is not trusted by the browser and will issue an "unsafe" warning. Therefore, everyone must choose a formal CA organization, such as Symantec, Comodo, etc.
2. The system time is set incorrectly. If the computer system time is incorrect, it will also cause abnormalities in the https certificate. Just adjust the computer system time to be within the validity period of the https certificate.
3. The https certificate has indeed expired. Faced with such a problem, we can only re-apply to the formal CA organization to re-issue the trusted certificate.
