Does anyone know how to enable TLS 1.2 on windows 10 Chrome, Microsoft Edge, or Firefox please? I keep getting this error.

    Hi TinaMills-1271,

    Here are guides for the most common browsers:

    Microsoft Internet Explorer

    Open Internet Explorer
    From the menu bar, click Tools > Internet Options > Advanced tab
    Scroll down to Security category, manually check the option box for Use TLS 1.1 and Use TLS 1.2
    Click OK
    Close your browser and restart Internet Explorer

    Google Chrome

    Open Google Chrome
    Click Alt F and select Settings
    Scroll down and select Show advanced settings...
    Scroll down to the Network section and click on Change proxy settings...
    Select the Advanced tab
    Scroll down to Security category, manually check the option box for Use TLS 1.1 and Use TLS 1.2
    Click OK
    Close your browser and restart Google Chrome

    Opera

    Open Opera
    Click Ctrl plus F12
    Scroll down to the Network section and click on Change proxy settings...
    Select the Advanced tab
    Scroll down to Security category, manually check the option box for Use TLS 1.1 and Use TLS 1.2
    Click OK
    Close your browser and restart Opera

    Apple Safari

    There are no options for enabling SSL protocols. If you are using Safari version 7 or greater, TLS 1.1 and TLS 1.2 are automatically enabled

    I hope this answers your question.

    1. open the command prompt.
    2. write down: hostname
    3. Again write down: whoami [ note: please open command prompt by administrator credentials)
    4. regiedit

    User's image

    1. User's image
    2. if hex value 1, that means TLS version 1.2 is enabled.
    3. If the hex value is 0, that means TLS version 1.2 is disabled.
