Secure Connection Fatal Error 300 / mini 26.0 & java 8.0

  • I can't get in to some website recently, but few day ago it's still acessible and now get this messege:

    Unable to complete secure
    You tried to access the address https://, which is currently
    unavailable. Please make sure that the web
    address (URL) is correctly spelled and
    punctuated, then try reloading the page.
    Secure connection: fatal error (300)
    The certificate is not known by its supposed
    issuer. It is not valid. In the worst case it may
    be used by criminals for fraudulent purposes.
    The website owner must immediately replace
    the certificate.

    Trying other browser loaded perfectly.

    Sorry English not my native languages.

  • When i try high or off modo it can be acessed
    any way to make the auto and extreme mode to access it again? Cause high and off take too much data.


  • I will look into that after Christmas break, until then you have to stick to High compression mode. Alternatively you may try to contact website administrators. Recently the certificate of the website changed, so that is likely related and they may know what exactly was changed and revert that.

  • @mahfudzevo the website now works in Extreme mode (without us doing anything) 🙂

  • Oh thanks, sorry for late reply.
