When I try to connect to a couple of our ESXi servers with my vSphere client I get the following error message:
"vSphere Client could not connect to "IP Address".
An unknown connection error occurred. (The client could not send a complete request to the server. (The underlying connection was closed: An unexpected error occurred on a send.))
I'm thinking this may have something to do with a version incompatibility but I'm not sure. Can somebody shed some light?

This error troubled me for quite a while, and since this thread is still the first google result, here is my solution.
It is quite simple actually, just "Restart the Management agents". As mentioned by VMWare knowledge base all you have to do is run:
from shell.
