Hi

Could you please any one help out to configure/Enable TLS 1.2 for SharePoint 2016 .
Network guy installed the TLS into the server, after this i not able access SharePoint site showing below error message
i.e

" Turn on TLS 1.0, TLS 1.1, and TLS 1.2 in Advanced settings and try connecting to <https://siteurl> again. If this error persists, it is possible that this site uses an unsupported protocol or cipher suit such as RC4, which is not considered secure. Please contact site administrator. "

I have done with advance settings from browser side but not resolved .

Can please advice what is the process to do fix this issue ?

Srinivas Are

    TLS 1.2 must be enabled your SP servers for TLS 1.2 to work. In addition to enabling TLS 1.2 make sure you have this key available as well on SP server.

    $registryPath = "HKLM:\SOFTWARE\Microsoft.NETFramework\v4.0.30319"
    $Name = "SchUseStrongCrypto"
    $value = "1"
    New-ItemProperty -Path $registryPath -Name $name -Value $value -PropertyType DWORD -Force | Out-Null

    $registryPath = "HKLM:\SOFTWARE\Wow6432Node\Microsoft.NETFramework\v4.0.30319"
    $Name = "SchUseStrongCrypto"
    $value = "1"
    New-ItemProperty -Path $registryPath -Name $name -Value $value -PropertyType DWORD -Force | Out-Null

    you can also use this utility to enable TLS 1.2 on server.

    Hi @Aare Srinivas Patel ,

    Please go into IIS on your web server check the site Binding.

    Check whether you selected SSL certificate or not. You have to select proper wildcard certificate.
