Disabling SSLv2/v3 and TLS1.0, 1.1 on clients

I am testing IISCrypto to disable old TLS versions and force TLS1.2, this is what I have left enabled (I have also disabled MD5 hashes): https://imgur.com/a/5ukm3KF

Now when i try to use the VMWare client to connect to and ESXI host or VCenter i receive:

---------------------------

Could Not Connect

---------------------------

vSphere Client could not connect to "10.1.100.114".

An unknown connection error occurred. (The client did not receive a complete response from the server. (The underlying connection was closed: An unexpected error occurred on a receive.))

---------------------------

OK  

---------------------------

The hosts I am trying to reach with the VMWare client are running 5.5U3B and VCenter 5.5 U3d, they are running on old hardware that doesnt support later versions.

Any chance I can get it to work?
