In another case, when the certificate is not in the trusted list of browser vendors, "SSL certificate error" will occur. You can install into your browser's trust list by manually adding a certificate. Trusted root certificates need to be embedded in popular browsers, such as IE, Firefox, Chrome, Apple and so on. If the browser encounters a certificate that is not signed by one of the roots, it indicates that it is not trusted, and visitors will see the message that the certificate of the web page is wrong. It is recommended to use SSL certificates issued by authoritative CA institutions.
The security certificate of the website is not trusted. Second, the certificate name "does not match"
When the domain name listed on the SSL certificate provided by the server does not match the domain name connected by the browser, there will be a case of "certificate name mismatch", which will lead to the error of the web page certificate. To start an HTTPS connection, the domain name on the certificate must exactly match the domain name in the browser address bar. ? It is recommended to fill in the domain name information correctly when installing and deploying SSL certificate, and check whether the entered address is correct when browsing the webpage.
The security certificate of the website is not trusted. Third, the SSL certificate has expired or has not yet taken effect.
When there is an "SSL certificate error", you must first confirm whether the certificate is valid, or it may be that the date of the computer system is wrong. You can determine whether the certificate is within the validity period by checking the effective start and end dates of the certificate information. If it is within the validity period, you need to check whether the computer date is correct. Otherwise, it is the second reason. The SSL certificate is not valid, so you need to contact the certificate issuing CA to renew it as soon as possible.
The security certificate of the website is not trusted. Fourth, this is caused by the server that supports SNI.
This is more like an internal problem between devices, but sometimes when SNI is not enabled, the client will communicate with the server name. Maybe SSL? /? The reason of TLS protocol error. ? The first thing you need to do is to determine the host name and port number of the server in question, and make sure that it has enabled SNI and is transmitting everything it needs.
