1. Question:
1. Details of the problem:
您的连接不是私密连接
攻击者可能会试图从 mirrors.hustunique.com 窃取您的信息（例如：密码、通讯内容或信用卡信息）。了解详情
NET::ERR_CERT_AUTHORITY_INVALID
- Illustration:
2. Error reason:
Some software installed on the computer system (such as installing fiddler) may cause the following errors to occur when using Chrome to access https websites. This article explains how to solve such problems: "Your connection is not a private connection", "NET::ERR_CERT_AUTHORITY_INVALID", "ERR_CERT_COMMON_NAME_INVALID" or "NET::ERR_CERT_WEAK_SIGNATURE_ALGORITHM".
2. Solution:
1. Method 1: Manually knock thisisunsafe (if it doesn’t work after knocking once, just give up. Because you may have to knock multiple times, 不推荐)
Because Chrome does not trust these self-signed SSL certificates, for the sake of security, access is directly prohibited. This isunsafe command indicates that you have understood and confirmed that this is an unsafe website, and you will be given access if you still want to access it.
2. Method 2: Ignore the certificate error (personal test, invalid, 403, and after refreshing the cache, "Your connection is not a private connection" occurred again, 不推荐)
- Ignore certificate errors: --test-type --ignore-certificate-errors
■ Add the suffix to the Google Chrome installation program: --test-type --ignore-certificate-errors
- access denied
HTTP 403: means Internet Explorer can connect to the website, but does not have permission to view the page.
- Possible reasons: The website has been migrated
3. Method 3: Add the current user’s certificate (failed)
-
Reason for failure: Because it cannot be found: issued to (CertificatetionAuthority of WoSign) and issued by (StartComCertification Authority)
-
Specific steps:
(1) First press the key combination win+r to open the run window, enter mmc and press Enter:
(2) After bringing up the console window, click File and select Add/Delete Snap-in Unit:
(3) Find the "Certificate" option, click "Add", and select "My User Account":
(4) Open the current user → Intermediate Certificate Authority → Certificate in order, find the CertificatetionAuthority of WoSign certificate on the right, right-click to open its properties, and disable it.
- At this step, not found: Issued to (CertificatetionAuthority of WoSign) and Issued by (StartComCertification Authority)
(5) Close the browser and visit the website again
