Some users may not know much about the https certificate, but it is actually a secure digital certificate, also known as the SSL certificate, configured on the server. The main function of https certificate is to verify the identity of the server and encrypt data transmission, which can enhance the security of the website. Therefore, installing the https certificate to the website is also valued by more and more webmasters, but when we install the https certificate, there will also be errors in the certificate, so what is the error in the https certificate? How should we deal with it? Anxin SSL Certificate will answer these questions one by one.

What is wrong with the https certificate?

1. The current computer system time is wrong, and all http certificates have issuance dates and due dates. Computer system time outside the valid time range of the certificate may cause the browser to prompt the website that the https certificate has expired or is not yet valid.

2. The https certificate of the website has indeed expired. According to the international standard for issuing https certificates, https certificates can not be issued for more than two years.

3. The site references other outer chains with deployed https certificates. If the certificate of this outer chain expires, it will also prompt the corresponding error. The terminal devices that can detect certificate errors in the outer chain are: mobile browser and IE6 on PC (those above IE6 are not prompted).

Solution to an error in the https certificate:

1. The time of the computer system is incorrect: adjust the time of the computer system to the validity period of the https certificate.

2. Https certificate expires: website owner is required to renew the certificate at CA, the https certificate issuing authority.

3. The https certificate of the website outside the chain of the current site expires: the owner of the website needs to revoke the certificate or renew the certificate to the CA institution.

Https certificate can not only protect the security of data transmission of the website, but also enhance the trust of the browser, at the same time, it can also improve the ranking of the website in the search engine, so it is necessary to deploy https certificate to the website.
