  • Secure connection failed, error code: sec_error_bad_signature

    I installed windows 10 today. Not when I go to sites such as amazon on google, I get an error.

    'An error occurred during a connection to www.google.co.uk. Peer's certificate has an invalid signature. (Error code: sec_error_bad_signature). The page you are trying to view cannot be shown because the authenticity of the received data could not be verified. Please contact the web site owners to inform them of this problem.'

    So boring, everything was ok until today. Bloody Microsoft! I have re-installed Firefox but that does not cure the problem. Am temporarily using Chrome that doesn't have the bug, I can buy things from Amazon and search in google and use my gmail and youtube accounts. Can someone help me please? Thank you very much.

  • Error code: sec_error_bad_signature on Facebook and other sites (Yahoo Mail) trust.

    I get the error above for Firefox and certificate on Internet Explorer and Google Chrome error. The connection problem is to the same sites on all three browsers. I changed the site to the "trusted sites" on IE, but also uncheck the "check editor / certification of server" blocks. I learned to switch to Firefox would solve the problem because it is inherent to Windows 8.1/Internet Explorer 11. This only happens on my desktop, but not on my book in Google Chrome. Any ideas or solutions on any of the browsers?

    First thought is that you should ask this in the forum, not on the forum of the Thunderbird and Firefox. You can get more help as this forum deals with any software Thunderbird mail client.

    which would indicate a bad sensor on one of your memory modules or riser:

    In the case of an error in probe (4SNS), to determine what type of sensor is referenced, look for his first letter, which should be 'I' for the current "V" or "T" for temperature, voltage.

    Then check the second letter from the list below to see which component it refers to:

    A: ambient air sensor
    B: battery
    C: Central processors (CPU)
    D: DC (direct current)
    e: PCI-express slot
    F: FireWire port
    G: graphics processor (GPU)
    H: drive
    h: heat pipe (heat sink)
    L: liquid crystal display
    M: memory or the memory riser cards

    I would first install a monitoring app like Mac Fan Control of temperature


    to see of you can find a bad sensor by reading the memory riser card.

  • 4SNS/1/40000000 error code: VDOR - 18.678 & 18.679

    MBP early 2011: I just ran the AHT twice, the first round gave me an error code of 4SNS/1/40000000: VDOR - 18.678, second inning gave the code 4SNS/1/40000000: VDOR - 18.679. Does anyone know what are these error codes? My best guess is probably the RAM, I have (2) modules of 8 GB 1600 Mhz DDR3 OR wireless networking equipment installed. I've noticed recently while multitasking, the wifi connection seems to cling and web pages will not load/downloads will pick up. But the way in which applications will be blocked for 60 seconds makes me think of a bad situation of RAM I have had in the past. Any help would be greatly appreciated since the nearest bar genius lies in 2 1/2 hour. Thank you!

    No RAM - 4SNS is a sensor error.

  • Transcend Jet 360 Lite SD care & "the operation cannot be completed because an unexpected error occurred (error code - 50)"

    Have used the SD Transcend 360 256 MB card for data storage with success during the last 6 months on my MBP to mid-2014.  Installed their wake from sleep early support software.

    Above error code invite you in this context: I wake up Mac in the morning after sleep.  Transcend icon "wake up" and appear on the desktop (as it should).  I check disk utility and the card is recognized.  HOWEVER, about 1/3 of those mornings, despite appearing and functional map icon (folder open when I click on it), when I try to write/copy a file or folder to it, I get the above error code?  For about a week I missed that everything seemed normal.  My current 'fix' is to eject the card (requires a 'forced ejection"which I'm concerned could damage the card?), but the card ejects without delay.  90% of the time when I remove and reinsert the card, the operating system recognizes, all right.  (There are a dozen times when I had to reboot for it to be recognized.)

    All the others did this experiment with the Transcend (I submitted a request for tech support to them with a persistent response of 'Question Mac'... (LOL).  This error has been noted several times on the Forum discussion, but in the context of external drives and with no apparent solution.  FYI, I use the Transcend (in addition to external systems) b/c it works essentially like a hard drive internal and I use it mainly for Google Drive perfectly... except for the above inconveniences.  Thanks in advance!

    This is the Office Mac Pro forum. I asked that your post moved to the forum of laptop MacBook Pro or another appropriate forum.

    You... don't even leave the website to load. Try again. Try again. Try again. Try again. Try again. Try again. The certificate of the site is very well as evidenced by SIX different sites of the verification of the SSL certificate. I can't add an exception because FF is unable to obtain the certificate.

    I tried to clear all - cache, cookies, history, blah blah blah

    I am so bored of you people cost me more time.

    It's fine in IE and Chrome.

    If I didn't need Firebug, I would switch to Chrome right now.

    edited because of the language according to the rules-forum-guidelines

    You're right, it is not sensible.

    Never made an exception for the site.

    FINALLY, what worked was rename the cert8.db file in the profile folder so FF could generate a new. Then FF grabbed the cert very well.

    Thank you for the help, sorry for the earlier rant.

  • How to fix error code 22 on iphone 5 s?


    My phone is iPhone 5 s 16 g and I just finished upgrading my operating system iOS 9.3.4. After updating because when I was upgrading my PHONE when it was still in lower versions that he deleted files, music, photos and other downloaded etc. apps which is I think normally during the upgrade, but then when the latest version (iOS 9.3.4), it didn't remove a single file. I just wondering and I wanted to ask if this is really what happens when upgrading to the latest version of the operating system? My other question is what you mean by error code: 22? I tried to connect to my facebook account (it is after the upgrade), when I press the log in a pop out window and say "will record in Failed" and talk about the error code 22. How can I possibly fix it immediately because I can't use my apps if that happens?

    I haven't done any troubleshooting yet because I don't really know what to do.

    We hope to receive an immediate response to this topic.

    Thank you.

    Carmel Burgos

    Hello Carmel, to answer your questions:

    (1) iOS updates should not delete all data on your phone, the system is updated but nothing else changes. All data and settings should remain the same. This is the normal behavior.

    (2) to find mistakes Apple checkbox. However 22 is not there. 21-23 can help:

    Get help with iOS update or restore errors - Apple Support

    (3) for the Facebook app, you may need to contact Facebook because that's their problem. Alternatively, you can delete the app, reboot the phone and re-install the application. This works for many. Good luck.
