Unable to read shared variable from compactRIO

I am building a simple project: the host computer talks with compactRIO controller through shard variables.  The host computer writes data to shared variable, crio reads data from shared variable. The shared variable is network-published.  However, if I let the host computer host the shared variable library, i.e., put the lvlib file on "My Computer", crio can not read from shared variable, and it returns error code "-1950679035" with source ni_tagger_lv_Read.  If I let crio host the shared variables, crio can read and host can write.  So what's the reason that crio can not read the shared variables when the host computer is hosting shared variables?
crio has installed variable client support and network variable engine.
