Opera sites access issue

  • So, here is a thing, around a week ago for some unknown for me reason opera started to spam "invalid certificate" on almost every site (including the ones like google, wiki etc). I tried to clear cookies, reinstalling opera, but i still getting this messages, even though now not on all the sites. On top of that now some sites are not accessible because of "Your connection is not private" problem...

    The CA that is not seems to be reliable named WinRootCA. I couldn't find anything about it in the internet neither any files on my pc with some similar naming. I tried to install opera on my laptop and it's working absolutely fine.

    How can i fix this thing? Both private connection and certificate one.

  • Version of Opera and OS....?

  • Windows 7 SP1
    Opera 12.17 and Opera 40.0

  • Opera 12.17

    Try updating to 12.18 as it was released to address issues regarding secure connections.

    Opera 40.0

    It happens on that version too?

    When you try to go to a page and get the error, what info do you get if you click on the globe at the address bar?

  • Try updating to 12.18 as it was released to address issues regarding secure connections.

    Well... in version 12 i had an issue with certificates only, it will spam me with any possible thing, like google.doubleclick, img0000_something, etc

    It happens on that version too?

    Yes, unfortunately. But not on all sites. Some will work, some will have private connection issues, some will have certificate issues.

    When you try to go to a page and get the error, what info do you get if you click on the globe at the address bar?

    If I try to open facebook i will get a private connection problem and globe would have next text:

    Unprotected connection
    www.facebook.com
    The connection is not protected.

    First visited: Saturday, October 1, 2016
    Certificate: *.facebook.com

    Connection: TLS 1.2 AES_128_GCM ECDHE_RSA (P-256)
    Errors: Server's certificate is not trusted.
    Server's certificate cannot be checked.

  • Yes, unfortunately. But not on all sites

    Have you checked with a clean separated(standalone) installation or with a clean profile?

    Do you use any extensions? What about Anti-virus or similar software?

  • Have you checked with a clean separated(standalone) installation or with a clean profile?

    If i understand you correct then yes, i checked it with a clean installation. I uninstalled all operas i had and cleared all files related ti them - cookies, register, etc. And still got this issue.

    Do you use any extensions? What about Anti-virus or similar software?

    The only one i used was Adblock, but i uninstalled it in one of the first tries to figure out this problems.
    About anti-virus, i'm using Baidu Antivirus 2015.

  • Looks like you may have some local https intercepting software active. Similar problems do occur for example when using (very good) Fiddler tool for decrypting https traffic, but not adding its certificate to trusted roots.

    Do other browsers, esp Chrome and IE, behave better?

    Scan your machine with different (online) antivirus/antimalware utilities (I can recommend ADWCleaner), maybe some of these reveals something.

    Does Baidu antivirus have option to 'protect' your internet connections? If yes, just disable such protection.

    Can you post some untrusted server certificate data in detail (including certification chain or even export certificate and link somewhere)? Looking at such certificate it would be quite clear, is it real or inserted by some rogue process.

  • Do other browsers, esp Chrome and IE, behave better?

    Firefox works absolutely fine. Chrome has the same private connection issues.
    I uninstalled IE, so can't tell about that one.

    Scanned, cured, still the same.

    Will do that after i come back from work today

  • That's opera 12.18 issues. Even if i install english version it would still be in russian for some reason...
    I just hope it's still gona be enough to understand it.

    And that's opera 40.0 one.

  • Chrome has the same private connection issues

    So it seems something related to Chromium.

  • Russian is not problem 🙂 What is visible on second tab (Состав) of O40 (get.adobe.com) cert? Путь сертификации (Certification path) is probably empty?

    I forgot to ask - does your Internet connection use proxy? Internet options, Connection, LAN Settings - what options are there selected?

    Oh, forgot about those. Here they are:

    If i understand you correctly, then no, i'm not using any proxy.
    That's what you're talking about, right?

  • Thank you for screenshots! Hard to say precisely, but certificate doesn't fully match to normal get.adobe.com one. It is either forged (what I do not consider likely, although it is possible) or your Windows cryptography engine is somehow broken. WinRootCA may hint at it too - usually such name is assigned to domain CA, which should not have any connection to public websites certificates.

    I uninstalled IE, so can't tell about that one.

    I didn't pay enough attention to this earlier. First, IE cannot be uninstalled from windows efficiently, but it can be hidden and rendered unworkable. And this 'uninstalling' may affect cryptography too, somehow. What software did you use to uninstall it?

    Unfortunately I haven't seen any good tools to repair crypto for Windows 7. There was good utility for XP (dial-a-fix), but this doesn't work on W7. Probably there are some articles on MSDN or MS Technet to hep in this situation.

    What about Firefox - IIRC it doesn't use Windows internal crypto engine, at least not in full extent. IE/Opera/Chrome do.

  • It is either forged (what I do not consider likely, although it is possible) or your Windows cryptography engine is somehow broken.

    Yes, that was my thought aswell, and that's why I checked my pc for any hint about that winrootca on both my pc and laptop and on internet aswell, but couldn't find anything.

    Well, yeah, I didn't actually uninstalled it, but isolated it and I did that ages ago, so i can hardly remember what programs I used... probably some guide on the internet.

    What about Firefox - IIRC it doesn't use Windows internal crypto engine, at least not in full extent. IE/Opera/Chrome do.

    Yeah, as i said already, FF works absolutely fine for me.

  • WinRootCA may mean Windows root CA (certificate authority), which can mean any (trusted or untrusted root) certificate inside Windows certificate store. Certainly it is not any real CA, otherwise you should find its certificate in windows certs or everywhere in google.

    Unfortunately I can't be more specific; this kind of problem is rare and I have seen that only once, on WinXP and fixed crypto with tool, noted above - not possible in Win7. You may search on internet, how to check and restart cryptographic services on windows - but if this service is not running, then you should have more problems than just cert errors on internet.

    You can run system file checker (https://support.microsoft.com/en-us/kb/929833), this may find something broken and even fix it or at least give further hints. It may restore IE 🙂

    If you can rememeber, what did you install or reconfigure before problems begin, this may help. Some windows or other software update may had some effects either.

  • Well... I didn't installed anything new for a while now...so hard to say, it just randomly started to pop up this issue. I will probably check that system file checker and if it wouldn't help then the only option would probably be to reinstall OS.
