Lỗi the connection to this website is untrusted năm 2024

The accessed site prompts "connection is not secure" after SSL certificate deployment. Has the certificate deployment failed?

The certificate has been successfully deployed. This problem occurs because the browser considers the access to sites using HTTPS protocol unsafe when the pages contain unencrypted HTTP contents. In this case, code needs to be modified.

For frontend modification, here are some guidelines:

Use the relative path to reference resources.

When referencing the absolute path, use // to reference resources. For example, //img.qcloud.com/example.png indicates compliance with the protocol of the current page, and the browser will automatically complete it.

(1) Error in your system's date, time, or time zone, which throws off certificate validity checks. Sometimes allowing computers to use an internet-based time source can introduce this problem.

(2) Firefox not being set up to work with your security software that intercepts and filters secure connections. Products with this feature include Avast, BitDefender, ESET, and Kaspersky; AVG has a Search Shield feature which can cause this error on search sites.

(3) On Windows 10, Firefox not being set up to work with the parental control software Microsoft Family Safety.

(4) Malware on your system intercepting secure connections.

So... which is it?

If you have any of those specific security products, that would be the first thing to check. We might be able to assist with specific next steps based on what you have if you tell us.

To investigate further, you could inspect the certificate for a site that doesn't use HSTS. That could either be a site for which you already added an Exception, or another site. Here's an example using my test page:

https://jeffersonscher.com/res/jstest.php

You likely will get an error page. Expand the "I understand the risks" section and look for an Add Exception button.

Note: You don't need to complete the process of adding an exception I suggest not adding one until we know this isn't a malware issue but you can use the dialog to view the information that makes Firefox suspicious.

Click Add Exception, and the certificate exception dialog should open.

Click the View button. If View is not enabled, try the Get Certificate button first.

This should pop up the Certificate Viewer. Look at the "Issued by" section, and on the Details tab, the Certificate Hierarchy. What do you see there? I have attached a screen shot for comparison.

Internet Explorer 11 has been permanently disabled through a Microsoft Edge update on certain versions of Windows 10. If any site you visit needs Internet Explorer 11, you can reload it with Internet Explorer mode in Microsoft Edge. We recommend you use Microsoft Edge for a faster, more secure and more modern web browsing experience.

Symptoms

A user who tries to connect to a secured Web site by using Windows Internet Explorer may receive the following warning message:

There is a problem with this website's security certificate. The security certificate presented by this website was not issued by a trusted certificate authority.

Security certificate problems may indicate an attempt to fool you or intercept data you send to the server. We recommend that you close this webpage and do not continue to this Web site.

Resolution

To resolve this issue, an organization that hosts the secure Web site can purchase a certificate for each Web server from a third-party provider. Or, the organization can install a Microsoft Enterprise certification authority in the Active Directory forest. Then, the organization can use this certification authority to generate a certificate for each Web server.

Note Users of client computers that do not belong to the organization's Active Directory forest can visit the certification authority Web site to download the certificate.

Workaround

To work around this issue, install the Microsoft Windows Small Business Server 2003 (Windows SBS) self-signed certificate on the client computer. To do this, follow these steps:

1. In Windows Internet Explorer, click Continue to this website (not recommended). A red Address Bar and a certificate warning appear.
2. Click the Certificate Error button to open the information window.
3. Click View Certificates, and then click Install Certificate.
4. On the warning message that appears, click Yes to install the certificate.

Notes

• In Windows Vista, the same issue occurs with self-signed certificates. However, the option to install certificates is not available unless you run Windows Internet Explorer with administrator rights. To do this, right-click the Internet Explorer icon, and then select Run as Administrator.
• When the client computer connects to a Web server that is running Windows Server 2003, the client computer reuses the certification authority certificate. The client computer does not use another certificate that is signed by the certification authority.

More Information

This problem can occur if the client computer's clock is set so that the date/time is later than the expiry date of the web server's SSL certificate.
