  1. terrible article. You just write a bunch of buzz words to get your article more hits… the “solutions” you provided here are not even solutions, they are temporary things to get around the problem, like preventing the warning from appearing, or add an exception. This doesn’t work when you are getting “NET::ERR_CERT_AUTHORITY_INVALID” from ALL https sites… and change your clock back?? So that we can go before the certificate expired? Are you serious? This isn’t a fix… I dont want to suppress the error, I want to FIX the error. The only step here that might fix the problem is clearing your data and even that didn’t work… I’m sick of these fake articles

      1. Terrible attitude, attacking someone for making a valid point.

        Katies reply is absolutely on point. If you are getting NET::ERR_CERT_AUTHORITY_INVALID for known and trusted sites you have issues with your ca configuration on your machine, supressing the warnings does not fix the issue. If you are getting this error on known sites, you may have issues with malware and or miconfiguration.

      Hi Katie,
      Just check your proxy setting and disable the proxy from LAN .
      May be you have tried to install malicious program which changed your proxy and try to intercept your network.

    2. I completely agree. Suggesting that people just bypass these security features is a horrible idea.

    3. Simon Raistrick

      guy has no clue – basically ‘if you get a security error, just remove the security’ – hopeless.

  2. HI,

    This depends on what type of authentication you are connected to. If you are connected to wpa2 passkey, then you are authenticated first and then get the IP address, henceforth you are validating the server cert. But this is hectic when you connect using byod as you can get IP first but they are not authorised.

    Here either you need to install a valid wild card cert with full domain or you need to manually install the intermediate cert.

  3. Hi all, since I racked my brain for two weeks now with the same problem, I wanted to share how I eventually fixed it, even if this solution may not apply for everybody: in my case (Windows 10, Google Chrome, Kaspersky Internet Security 2016 installed), it was the virus scanner, or more precise: a configuration setting. Of course I wanted to keep my Kasperky scanner. My version is in german, so I try to translate: when opening the Kaspersky GUI, navigate to settings -> extended -> network settings. There are 3 options how to deal with secure connections (means: https). The options are to (1) not scan them at all (which I feel is ok, if they are secure and the certificate is correct and trusted), or additionally scan them (2) with asking or (3) always. in my PC option (3) was active, maybe that is simply the default. The dialogue comes with a explicit warning that some website may not be accessible anymore if the scan of secure connections is enabled (which I only learned when I stepped through all the configuration options…). end of the story: I disabled the scan of secure connections (which I believe is not really a security flaw, they should be secure by means of using SSL alone already), after this the https sites in chrome worked again. Kaspersky does not report any reduction in the security level (like it would do if you disable complete modules).

    Hope it is of help to anybody..
    cheers, Stefan

    1. this one works, but removes safe money, under the same section just below it says ADVANCED SETTINGS, SSL 2.0 protocol. i unchecked this. it worked for me.

  4. I just discover a solution.

    firstly I tried everything as said above but no luck. I also tried other solutions from different forum but no result.
    At last I thought my Antivirus might not working. so thats why I removed my AV(ESET 7) and reiinstall it (ESET 9).
    but before doing any virus/malware scanning I checked Chrome for the error.
    And to my surprise error vanished.
    I dont know what logic behind that but AV might be interfering with certificates.
    You should try this.

    And I also Agree that Solution given on this site is no solution at all. You should find your own solution. Best luck.

    Hello Guys,
    I don’t know whether this solution will work with everyone or not, but it worked for me. This error is actually being caused by a malware. There are two simple steps to solve this –
    1. Open your task manager when this error occurs. You will find a process, something like – HomePageDefSrv.
    2. Find it’s location in your computer by browsing the process properties. Go to the folder and uninstall this HomePageDefSrv malware. Delete the folder.
    Bam!! Issue solved.

  6. Actually the issue is your PC or User settings do not have the CA for this certificate in your trusted root store. As an example i got this error when exploring free public certificates for my home network. was giving me this error when I navigated into its website. The eazy fix is search in google for “Root Certificate Download” and alos the keyword for the website. IN this case There was a location for me to download the Root.CRT, right click on it in windows, and select to install it. Follow the defaults on the all the prompts and then close and reopen your browser. Voila. Problem Solved.

  7. I too had a same problem . I was getting the error continuously. then I uninstalled my recently installed CC cleaner ..then problem resolved. I think it had modified some certificates.

  8. You forgot to add “turn off the computer” I did this and the message went away for me. I think this is a better solution, because it doesn’t bypass any security.

  9. I resolved such issue by cleaning all browsing data in Chrome.
    This may not be a solution for most of you, I just would like to let you be aware of this.

  10. Have tried all of the suggestions above, but seemed don’t work.
    I recently changed my website hosting and use the same domain.
    it constantly showing this error even if I open it from other computers out there.
    Any suggestions please.

  11. To FIX NET::ERR_CERT_AUTHORITY_INVALID Error XP CHROME go to CONTROL PANEL -> Add or remove programs -> Add/remove Windows components, scroll down and check UPDATE ROOT CERTIFICATE -> Next -> Finish and VOILA !!!!

    Your certificate is UPDATED !!!!
