Cannot add the ESX host to vCenter Server

Adding the ESX host to vCenter Server fails

You see the error:

In the /var/log/vmware/hostd.log file of the ESX host, you see entries similar to:

[<YYYY-MM-DD>T<time> F63BFB90 warning 'Proxysvc Req00117'] Writing response from localhost:8307 to client failed with error N7Vmacore15SystemExceptionE(Broken pipe).
[<YYYY-MM-DD>T<time> F58F5B90 error 'App'] Failed to send response to the client: Connection reset by peer

</time></time>

Generating a new SSL certificate on the ESX host or reinstalling vCenter Server does resolve this issue

Enabling trivia logging does not provide more information on this issue

Cause

This issue occurs when a SSL record is received with an incorrect Message Authentication Code (MAC), which may be caused by network issues. For example, some packets may be lost during communication. In this case, the MAC calculated at the receiver's end does not match the MAC calculated at the sender's end.

Resolution

To resolve this issue, remove the virtual NIC from the vCenter Server virtual machine and add a new NIC for the virtual machine.

Note: If the issue persists, try adding a vmxnet3 virtual NIC.
