Google chrome SSL certificate errors

Google Chrome offers comprehensive compatibility, privacy, security, speed, low memory consumption, clear design, etc. to their valuable users.Google Chrome became the primary web browser in competition of other web browsers on various desktop and mobile devices.

There are mainly two types of SSL Certificate Errors that are possible in Google Chrome
1) SSL Errors due to user’s System
2) SSL error due to improper installation.

1. System Time 
                               When the user’s clock is not set on current time Chrome will display an error as “Your connection is not private” or “NET::ERR_CERT_DATE_INVALID”, to fix this error you just need to update your date and time with the current time zone.
2.This webpage has a redirect loop
                             When a user tries to access a secured web page, due to overload in cookies, Google Chrome will try to redirect that page many times and finally it will display an error as “This webpage has a redirect loop” or “ERR_TOO_MANY_REDIRECTS”. To fix this error you just need to delete all the cookies for that website.
3. Remove Website Cookies in Chrome?
                          Click on Settings > Show Advanced Settings…
Now in the Privacy section, click on Content Settings…
A Content Setting popup will appear, in Cookies click on All Cookies and Site Data…
In Search cookies, type the website for which you wish to remove cookies and then click on “Delete this Item” button to remove cookies.
4. Your Connection in Not Private NET::ERR_CERT_AUTHORITY_INVALID Chrome Error
 NET::ERR_CERT_AUTHORITY_INVALID
            To Fix “Your connection is not private error”
Check your network connection, if it is not active then turn it active again. And try to access that website again.
If there is conflict in a cookie, this error may be displayed, better you clear all the cookies of that particular website (how to remove website cookies is displayed above) or else try to access that website in incognito mode (Ctrl + Shift + N).
If you are using an older version on Operating system, then you must update it.
If any antivirus software is installed, you should turn it off as few antivirus blocks suspicious HTTPS traffic sometime.
5. Your Connection in Not Private, with Chrome
If the certificate authority of that website’s SSL Certificate is not valid or the website is using self-signed SSL certificate, then chrome will display error as NET::ERR_CERT_AUTHORITY_INVALID Chrome; As per the CA/B forum rule, the certificate authority must be the member of CA/B forum and its source will also be inside chrome as trusted CA.
To solve this error, contact the website administrator and ask him to install SSL of a valid Certificate Authority.
6. Your Connection in Not Private, with NET::ERR_CERT_COMMON_NAME_INVALID
          Google chrome display “ERR_CERT_COMMON_NAME_INVALID” error because of the common name user has entered is not matched with the actual common name of the SSL Certificate. For example, if a user tries to access www.google.com but the SSL certificate is for google.com then Chrome will display this error.
To get rid of this error, the user should enter the correct common name.
7. “Server has a weak ephemeral Diffie-Hellman public key” or ERR_SSL_WEAK_EPHEMERAL_DH_KEY
             Google Chrome displays this error because the security code is outdated and users not allowed to access that website. To prevent the risk of information and identity theft chrome blocks access to that website.
To fix this error, contact the website administrator and ask him to disable DHE codes and add support for ECDHE codes in the server. If the ECDHE codes are not available, then he can go further with plain RSA.


8. “This webpage is not available” or ERR_SSL_VERSION_OR_CIPHER_MISMATCH
             Chrome displays these errors if some security codes are missing and the website is running with an outdated SHA algorithm or system’s TLS version is outdated.
Know how to solve This web page is not available and ERR_SSL_VERSION_OR_CIPHER_MISMATCH errors.

To get rid of this error, contact the website administrator and ask him to reinstall the SSL certificate on a server with the updated version of the SHA algorithm as SHA-2. The user also needs to access a website with the highest version of TLS as TLS 1.2.
9. Expired SSL Certificate
     In case, if your website got an SSL certificate, which might expire then Google Chrome will show an error and certainly, it will block all kind of access. It’s a matter of rapid action that you need to take. Contact website admin to renewal or new purchase of an SSL certificate and get it to reinstall.
10. SSL Not installed correctly
    An SSL Certificate must be installed correctly to access website properly without any error, if there is some SSL installation problem, chrome will display error.
