When we are browsing the Internet, we often encounter such a situation, that is, https cannot be accessed. Is this due to the expiration of the https certificate, or because of https errors? what are the solutions for https inaccessibility? let's take a look at it.

In fact, because of the unique nature of https, it is often possible to have https errors or https can not access the situation. So why is the https inaccessible? in fact, this is due to the unique situation of the https certificate. The reason why https cannot be accessed is generally due to the fact that browsers consider off-site resources that are not HTTPS under the HTTPS protocol as unsafe resources and block them and prompt errors by default. This is why the images, CSS and JS accelerated by CDN under the non-HTTPS protocol cannot be displayed under the HTTPS page. It is OK to keep these resources locally, and most of the time we need HTTP and HTTPS resources to coexist. There are two ways to solve the problem, one is to make all the resources local, and the other is to transform external resources. If the whole site does CDN acceleration, you can do localization without off-site resources. If your own server does not use these resources, but only references off-site resources, you need to make the following modifications.

What are the solutions to the inaccessibility of https? generally speaking, you can reconfigure the https certificate or modify the relevant parameters. Or change the link. If you get a non-https link from an external website, you can ask whether the other website supports changing http to https directly. If not, the link may not be accessible if you directly change http to https. You can also ask whether the other website can provide a link with https.

So this is the relevant situation that https cannot access. If you need to solve the problem, you can refer to the above method.

SSL certificate securely encrypts the website, which can effectively prevent hijacking, prevent your website from being maliciously implanted with advertisements, prevent tampering and monitoring from leaking users' passwords, and optimize the SEO ranking of search engines with SSL certificates.
