[Koha] z3950 internal server error

Dear Friends, I write regarding my z3950 problem. We installed Koha 2.2.9 in Fedora Core 4. I configured Z39.50 Server with LOC. While try to search LOC using z3950 it opens the window showing the default server (LOC). And shows the following error message when click on “Search Internet” button, “Internal Server Error The server encountered an internal error or misconfiguration and was unable to complete your request.” Can you help me solve this problem, Vimal Kumar Asst.
