How to get rid of this error?

Everything seems normal until I use CCleaner to clean up something. I let it run, scan and delete automatically and after that, I didn't check again.

One day later, when I access any sites with HTTPS, everything turns into this error and prevent me from access those sites.

Google Chrome says: Your connection is not private, NET::ERR_CERT_INVALID.

What should I do now?

It seems that I have deleted some files that Fiddler needs?

I found some guides in Google.com, which are related to this error to refer, such as:

https://usefulpcguide.com/16666/your-connection-is-not-private/

Not nothing is useful and help me get rid of it.

Well I don't really know what exactly CCleaner removed but reinstalling Fiddler and then reinstalling its root certificate should get you back on track.

I got the same issue, tried a few solutions before but it didn't work. The link you provide didn't work either.

Hi Tim,

At this time, the only option we can provide is to uninstall and reinstall Fiddler using Add or Remove Programs.  Are you able to uninstall and reinstall Fiddler?

Please give this a try and let me know the results. Thank you and I look forward to your reply.

I don't know whether this issue has been fixed yet but in my case, I have followed the suggestion of Yovtchev, which is to reinstall Fiddler. In that time, I also uninstall Avast antivirus (I have recently installed) because someone told me that it can block HTTPS connections.

Once I done those steps, this SSL issue gone and never return. So I would suggest you to do the same as me to try out. As of the guide I referred before, it seems the post was removed, but let's try this guide, comes with more information.
