HTTP Connectivity Error: ReceiveFailure

HTTP Connectivity Error: Receive failure typically indicates that the connection was closed by the remote host. This can happen if the remote server does not trust the certificate presented by the Local Server.

HTTP Connectivity Error: Ensure that the certificate of the local server and remote server are both valid, have not expired, and contain valid subject name. In addition, ensure that the certificate chain of both Server(s) are valid. Ensure that the certificate chain of the local server is installed on the remote server and vice-versa. The most up-to date certificate chain that was used to issue the server certificate must be present.





CAUSE
This issue occurs because Microsoft Office Communications Server 2007 does not operate correctly if there are too many trusted root certification authorities installed on the computer.
