After checking the code by your exception's stacktrace, I found this issue was caused by the service you use for server hasn't been configured.
For example, if you set serviceName as "remoteProcess" for server:
<add name="Kerry's Remote Process Server" serviceName="remoteProcess" ip="Any" port="911" mode="Async">
then you must define the service "remoteProcess" in services node:
<add serviceName="remoteProcess" type="RemoteProcessService.RemoteProcessServer, RemoteProcessService" />
On the other hand, I'll give proper exception/log message when this kind of error occurs.
