Your connection is not private



  • Suddenly stared getting the error "Your connection is not private" on facebook and you tube....Was working fine before.....the problem seems to be intermittent...... Doesn't seem to affect any other sites.... Not sure but believe it is related to updating my Opera to 12.18. Understand it was some type of security update...and believe it has changed some settings.... TIA



  • And how it is a topic for Vivaldi browser?



  • Could not access those sites among others from Vivaldi,



  • Please give us a hint:
    Which Operating system and version?
    Which Vivaldi version?
    Which URLs where it does not work?

    According to Opera's 12.18 release message: "…we’ve made a few changes, with a focus on the security aspect. The most important change is the support for ECC cipher suites used in secure connections. Another addition is GCM. Opera 12 now supports the same set of ciphers as other modern browsers. We have seen that many domains are relying on ECC certificates, thus making Opera 12 unable to connect. Similarly most clients using TLS have deprecated RC4 from the list of secure ciphers. We have done the same in this update. There is a setting to turn it back on, in case you need it. Since more servers are supporting TLS 1.2, we have enabled that by default."

    It's hard to see how Opera adding additional cipher support for a handful of ephemeral eliptical ciphers and tweaking TLS protocol settings within its own Presto browser resources and files would have any effect outside of Opera, particularly upon a chromium-based browser like Vivaldi, and the way it handles certs and ciphers.

    I don't know if it's related, but this did recently start happening to me for twitter**.**com in Chrome and Vivaldi, on my Mac laptop (OS X 10.11.3). Firefox and Safari are showing the site fine, and an install of Vivaldi inside a Parallels VM of Ubuntu on the same laptop gets Twitter fine.

    Hm, for the "VeriSign Class 3 Public Primary Certification Authority - G5" certificate, OS X Firefox and the Ubuntu VM Vivaldi are reporting a serial # of
    18:DA:D1:9E:26:7D:E8:BB:4A:21:58:CD:CC:6B:3B:4A

    While OS X Vivaldi and OS X Chrome are reporting for me a serial
    25 0C E8 E0 30 61 2E 9F 2B 89 F7 05 4D 7C F8 FD

    I'm not completely sure, but I seem to recall that a lot depends on where the browser accesses the certificate storage for a given site cert. It's my understanding that chromish browsers (Vivaldi, Chrome, new Opera) use the OS's cert store, whereas other browsers like Firefox or Olde Opera may access a local cert store updated via the browser maker's servers. If so, that could perhaps contribute an explanation for variances like you describe. It's been a while since I walked down this particular lane, so I may not be current with my understanding.

    Hmm, if I go to
    vivaldi://chrome/settings/search#certificates
    Clicking takes me to the OS X certificate store, which has the "18 DA D1 9E 26 7D E8 BB 4A 21 58 CD CC 6B 3B 4A" serial certificate.



  • The serial is 18 da d1 9e 26 7d e8 bb 4a 21 58 cd cc 6b 3b 4a on Windows 10 cert store and in Firefox cert store.



  • You should check:

    • Is your OS uptodate
    • is you certificate store uptodate
    • Is some proxy/router/gateway/security software intercepting SSL/TLS connections


  • Thanks Gwen-Dragon….it was a ui setting i mistakenly changed on my Fiddler Debugger....

    Thanks again for your time.

    Ok, found the problem. The invalid certificates (there were more than one) were in Keychain Access > Login, not Keychain Access > System Roots

    From there they could be deleted, and now thing are running fine. (For whatever reason, twitter.com immediately started working, once I deleted the problem certs, but it required Vivaldi restart for paypal.com to load.)

    My only remaining question is how they got there.

    The correct cert, as I had found before, was already in the System Roots keychain. Somehow Safari and Firefox had been already using that, while Chrome and Vivaldi were trying to use the problem one in the Login keychain. Now that the problematic G5 is gone (along with a couple of others – see attachments) everything seems to be working ok.

    I now see this issue with the same problem-causing certificate was mentioned on Stack Exchange as well.

    If you still can't resolve the problem, I found a useful guide from Google which may help.

  • A good guide for most users. Not by me as i am a IT pro ;)
    Thanks for sharing the link.
