0x80090331 The client and server cannot communicate, because they do not possess a common algorithm

[George Waters]

Hi,

Today, suddenly, from nowhere, my Windows 2012 R2 started to send to my mail system (for outgoing messages), also server it's not receiving mails:

0x80090331 The client and server cannot communicate, because they do not possess a common algorithm

My TLS configuration at HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols are (both server and client):

TLS 1.0
"Enabled"=dword:ffffffff
"DisabledByDefault"=dword:00000000

TLS 1.1
"Enabled"=dword:ffffffff
"DisabledByDefault"=dword:00000000

TLS 1.2
"Enabled"=dword:ffffffff
"DisabledByDefault"=dword:00000000

SSL 2.0 and SSL 3.0 are disabled.

Does anyone knows why I am getting this error?

Thanks in advance
