Seen this error for a while which didn't appear to impact anything. But it bothered me that this kept happening. Finally found the solution! Even though the error says "TLS client credential" it is actually an issue with SSL 3.0
There are 2 ways to fix this:
1st is manually (or GPO/script/etc.) add the following reg keys:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\SSL 3.0]
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\SSL 3.0\Client]
"Enabled"=dword:ffffffff
"DisabledByDefault"=dword:00000000
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\SSL 3.0\Server]
"Enabled"=dword:ffffffff
"DisabledByDefault"=dword:00000000
2nd option is use the GUI tool IIS Crypto. Available here: Nartac Software - IIS Crypto
Run that tool, uncheck SSL 3.0 in the Server and Client Protocols option and reboot. Log back in and run the tool again this time re-check the SSL 3.0 options. Reboot a 2nd time and issue is fixed.
