Hi All,Friends whenever I try to visit some popular websites using chrome browser It gives an error that "Your connection is not private" and there is a link to browse unsafe, I want to know
How to Fix "Your Connection is not Private" Error on Browsers?
Mainly in Google Chrome.
browsing in incognito mode is the option.?
 
Can you specify the website and try those from Firefox as well?

The error message has got nothing to do with your system. It is most likely because of website's SSL certificate not being updated.
 
Whenever I try to open any website for the first time it gives the above error.
I have attached the picture of the current status of this website, I marked the red crossed address bar with the green color. Thanks

Are you seeing these errors since November? If so it might be related to Letsencrypt root certificate expiration. Although windows 7 is supposed to take care of that, some settings might have messed that up.


Easy way to check if its due to this is to check the certificate of websites where you're getting this error. If all of them are issued by letsencrypt (like TE) then it's the most likely reason. It's easy to fix if that's the case


https://letsencrypt.org/certificates/ download the two root certificates from this site and import them in windows.
 
After installing the certificates from the given link i.e. der namely,
1.isrgrootx1
2.isrg-root-x1-cross-signed
3.isrg-root-x2
4.isrg-root-x2-cross-signed
still the problem remains and it returns the same error. See i am attaching the picture of the website.

It's probably the older cert still messing around. Just to confirm, can you post the certificate info of the website, something like this(click on the padlock icon in the address bar-> view certificate->certificate path)

In the site Certificate's first General tab it gives error that certificate has expired or is not yet valid.
In the second tab i.e. details-show: all there is a yellow sign in key usage and basic constraints.
In the third tab i.e. certification it says Ok.
See in the attached link, thanks in advance.

Ah, got it now. The DST Root CA X3(the one which expired) is messing with the system(the last screenshot). Just remove that cert from windows cert manager, it should work fine.

By using the command certmgr.msc in the run field and hitting enter key.
I found the list of all the certificates installed date and year wise.
I found DST Root CA X3 in two tab windows i.e. Trusted root certification authorities and also in Third Party certification authorities under certification tab.
Do I need to delete both of them? And also do I need to delete all the expired certificates installed in the OS? thanks.

Yeah


Not really necessary. If you face some particular issue then delete that.


I missed this part. Remove these as well, just keep the self signed certs.
Under Intermediate certification Authorities window I found the certificates issued by two authorities with the same name.How to identify the cross-signed one? I deleted the DST Root CA X3 certificate from both the tab windows.

Check the issued by column or check the details tab. If the issuer is DST Root CA X3, nuke it.
 
After disabling and deleting the DST Root CA X3 certificate it appears again in the certificate manager window and the problem of site not secure with double underline on https: remains as it was. I uninstalled the chrome browser and deleted all the history, passwords, cache, cookies, extensions run ccleaner software and downloaded the fresh copy of the chrome browser but it is again giving same error. I also tried with the Brave browser there also it is giving same error.

That's really odd. Just to confirm, you can see the X1 cert in Trusted/Third party Root Certification Authorises right?
 
It appeares again and again after disabling and deleting it, in the trusted certificates window.
This is the current state of the certification window.

I was talking about the ISRG X1 cert not the DSA CA X3.

I don't see it(ISRG X1) in the Trusted Root screenshot you just shared. Is it present in the Third Party Root Certificate? If it's not, add it manually to one of these places (by right click -> import i guess)
 
Now it is fine, I was simply left clicking from the mouse from the downloads so it went into the intermediate certification authorities, Now I went into the trusted certification authorities windows and by right click of the mouse after selecting import option I imported it from the downloads & now its all Ok, thanks alot. See the double signed cross error went off.
