What should I do if I encounter an SSL Certificate Error ?

SSL certificatesCauses of the error and how to fix it:

1. The SSL certificate contains a domain name that is inconsistent with **.

The domain name corresponding to each SSL certificate is unique and is a full-domain FQDN. When the certificate issued by ** contains the domain name and ** domain name.

inconsistency, the system will automatically send a report indicating that the certificate domain name does not match.

Solution: You need to apply for an SSL certificate again. If you have multiple sites with the same primary domain name, you need to apply for a multi-domain SSL certificate.

2. The certificate is not issued by a trusted authority.

This is because the certificate is not on the trusted list of the browser vendor. You can manually add the certificate to your browser's "trust list".

Solution: Select Content tab in the browser - Import certificates.

3. The certificate has expired or has not yet taken effect.

This is usually the case with the computer system.

If the date is wrong, the other is that the certificate has expired and needs to be renewed.

Solution: You can check the validity start and end dates of the certificate information to determine whether the certificate is within the validity period, and if so, check whether the date of the computer is correct. Otherwise, the SSL certificate is not within the validity period, and you need to contact the certificate issuer as soon as possible to renew it.

4. The page contains unsafe content.

It is currently advocated that every page use https, so all content must be https. This error will occur if you encounter **, js script, flash plug-in is called by http.

Solution: Change the calling element HTTP to https, and then refresh to test whether the SSL problem has been resolved.

5. When browsing the web, an SSL connection error suddenly pops up.

Solution: Press the "Win+R" key combination to open the run, and enter in the run box: Click OK to open "Internet Options"; Switch to the Advanced tab; In the settings box, select "Use SSL to use click-to-app" and click OK to restart the browser.

SSL certificate can encrypt the transmitted data and effectively protect user information, and has been widely used by various governments and enterprises

But in the process of installing and using SSL, people often encounter a variety of problems. Here, the three parties of Zhongke will take stock of some common problems and corresponding solutions for SSL certificates.

The certificate is not issued by a trusted authority:

Cause: This is due to the SSL certificate being used by the server, which is not issued by a CA authority trusted by the browser or is using a self-signed certificate. Method:

You can view the list of certificate authorities trusted by the browser in the "Tools Internet Options Content Certificates" of the browser, and try to choose a formal and professional service provider when purchasing a certificate.

Zhongke Tripartite Certificate Service cooperates with world-renowned CA institutions such as Symantec and CFCA to support all mainstream browsers.

**The certificate has expired or has not yet taken effect.

Reason: There are generally two situations when the browser appears this prompt, one is that the date of the computer system is set incorrectly, and the other is that the certificate has expired and needs to be renewed.

Method: First, you need to check the start and end dates of the certificate to confirm whether the certificate is still valid, and if the certificate has expired, you need to contact the certificate vendor to renew it as soon as possible. If the certificate is still valid, check whether the system date on your computer is incorrect, and correct it in time.

The page contains unsafe content.

Reason: If you need to access it through HTTPS, then every page and every element in it must be in HTTPS mode, if there are elements in **, such as: **, js scripts, flash plug-ins are called through http mode, such an error will occur.

The most common is to call the flash plugin: codebase=''。Method: Try to change the http call to https call, and this kind of problem can be solved after refreshing.

The domain name that is accessed is not the same as the domain name that is included in the certificate.

Reason: The domain name of each SSL certificate is unique. If the SSL certificate contains a domain name that does not match the domain name you are currently visiting, the browser will send such a message.

If your primary domain has multiple subdomains, you need to apply for a multi-domain or wildcard domain. Zhongke Sanfang provides multi-domain names and wildcard domain names of various brands, which can meet the needs of users for multi-domain names.

The installed SSL certificate is not the correct SSL certificate.

If this is the case, you can uninstall the original certificate and check whether there is any problem with the configuration and installation of the new SSL certificate.

An SSL connection error is displayed when browsing the web.

Reason: Since some web pages require the browser to support SSL to access, you can enable SSL to solve the problem.

Method: Press the "Win+R" key combination to open the run, enter "Internet Options" in the run box, switch to the [Advanced] tab, and check "Use SSL to use the click app" in the settings box and click OK to restart the browser.

Helpful. Questions.

Tried it. This will not work.

There are the following reasons for the SSL error on the Apple mobile phone: 1. The ** certificate accessed is not well deployed, or ** in addition to what fault causes the connection to not be able to connect, which needs to be consulted**. Just wait for the official solution.

2. If the identification error occurs in the mobile phone system, it can be solved by restarting the mobile phone. 3. If the mobile phone network is caused by an error, it can be solved by restoring the network settings.

Questions. Fart.

Check what is causing your phone.

Questions. No.

There is no reason why SSI will not be displayed.

First, the access certificate is not well deployed, or in addition to what failure causes the connection to be unavailable, this needs to be consulted. Just wait for the official solution. 2. If the identification error occurs in the mobile phone system, it can be solved by restarting the mobile phone.

3. Caused by mobile phone network errors, restore the network settings to solve the problem, the recovery method is as follows: 1. Find the "Settings" icon on the desktop and open it. 2. Find "General" and open it.

3. Pull the page to the bottom and find the bottom "Restore". 4. In the middle of the page, you can see "Reset Network Settings" and click it. 5. Enter the boot password here.

6. Click the red font at the bottom to confirm "Reset Network Settings", and the phone will start to enter the initialization, just wait. After the network settings are restored, you can connect to WiFi normally.

If SSL doesn't work, you can change your VPN connection.

Network problems, some wifi just can't log in, mine is also the reason I don't know, but it's good to change to 4G It can be used.

1. Use win+r to open the running window, enter the command and press enter.

2. Switch to Advanced Options, check Use, Use, Use, and click the OK button.

SSL Certificate Error 901 refers to the failure of the server's SSL certificate validation during an HTTPS connection. To solve this problem, you can try these steps:

1.Check System Time and Date: Make sure that the system time and date settings on your computer are correct. If the time and date are inaccurate, it may cause the SSL certificate validation to fail.

3.Update your operating system and browser: Make sure your operating system and browser are up to date. Updating the software may fix known SSL certificate validation issues.

4.Confirm the validity of the certificate: Check whether the certificate has expired or been revoked. You can view the certificate details by clicking on the lock icon that appears on the address bar of your browser. Make sure that the certificate is issued by a trusted authority and that there are no issues.

5.Check firewall and security software settings: Some firewalls or security software may interfere with the validation of SSL certificates. You can try disabling your firewall or security software and then try accessing it again**.

If you are an administrator, you may consider checking the SSL certificate configuration on the server to ensure that the certificate is installed correctly and matches the server's configuration.

Please note that if you are experiencing SSL certificate error 901 while accessing a public **, it may be due to a configuration issue with the network edge station itself. In this case, you can only contact your administrator or technical support for assistance.

Hopefully, these steps will help you resolve the SSL certificate error 901. If the problem persists, please provide more details so that I can help you further.

SSL Certificate Error 901 usually indicates that the client (browser) was unable to validate the server's SSL certificate. This can be due to one of the following reasons:

2.Certificate mismatch: The SSL certificate may not match the domain name being accessed.

This can be due to incorrect configuration or the certificate is not installed correctly. You can try to do this by entering the correct domain name or using a domain prefix (eg"www") to resolve the issue.

3.Self-signed certificates: If the server uses a self-signed certificate instead of a certificate signed by a trusted certificate authority (CA), the client may not be able to verify its validity.

In this case, you can try to trust the certificate manually or contact your administrator to obtain a valid trusted certificate.

4.Client time setting error: If the date and time of the client device are incorrect, it may cause SSL certificate validation to fail. Make sure your device time and time zone are set correctly.

The way to resolve this error may vary depending on the specific situation. If you are a visitor, you can try clearing your browser cache and cookies, and then reloading the page. If the problem persists, you can try accessing it with a different browser or device to confirm if the issue is related to a specific device or browser.

If you are an administrator or server operator, you should check the SSL certificate configuration of the server and ensure that the certificate is valid and installed correctly. You can also check the server's log files for more details about the error, and refer to the documentation of the SSL Certification Authority or contact their support team for professional help.

Reason for the expiration or invalidity of the SSL certificate:

1. **The SSL certificate is no longer valid.

The first thing you should do is check if the certificate has expired. SSL certificates must not be issued more than 13 months ago. Therefore, generally SSL certificates are only valid for one year.

**The administrator should check whether the certificate has expired from time to time, and if it has expired, please renew the certificate or purchase a new certificate in time.

If you apply for an SSL digital certificate on the official website of WoSign CA, then don't worry, we will start reminding and assisting you to renew the certificate 3 months before it expires.

2. Computer system time error.

If your computer's time is set incorrectly, it will also cause a message indicating that the certificate is invalid or expired. Please check whether the system time is accurate. If the system time is not within the SSL certificate start expiration date, the browser prompts that the SSL certificate expires or does not take effect.

3. The external connection certificate has expired.

If the first two methods don't work, check whether the external connection certificate has expired. This site refers to other external links where https security certificates have been deployed. If the certificate of this external chain expires, a corresponding error will be prompted.

The terminal devices that can detect certificate errors in the external chain are: mobile phone browser, IE6 on PC (IE6 or above is not prompted).

4. Insecure HTTP resources are loaded in **, or the certificate is not installed correctly.

If an HTTP resource is called in an HTTPS page, the IE kernel version of the browser will prompt that the page has an insecure factor. (Firefox and Google also have their own security tips).

5. Use a self-signed SSL certificate.

A self-signed SSL certificate is a certificate issued by an individual or organization itself. They pose a great security risk, are more vulnerable, and are not trusted by browsers.

6. Use certificates with poor versatility.

Similarly, using a poorly used SSL certificate issued by a small service provider is not trusted by browsers. Because the top layer of the certificate trust chain is the CA organization, and these small service providers lack the credibility of the CA organization and are not trusted by browsers. Therefore, it is recommended to choose a CA organization that has passed the certification of foreign WebTrust standards and has the ability of electronic certification services.

7. The SSL certificate does not match the ** domain name.

One of the necessary verification steps to apply for an SSL certificate is to verify the domain name, and the SSL certificate will be issued only after the domain name is verified. Therefore, the SSL certificate corresponds to the ** domain name, and the certificate of ** cannot be used for B**, otherwise the browser will also prompt "SSL certificate is invalid".
