Burak, This problem appears to be network problem between the IDV and the ADDE server. A few suggestions: Try connecting from a different network. It could be a firewall issue at your institution. (If there is a firewall, you need to ask the network/system administrator to allow the TCP connection to the port 112 in order to connect to the ADDE server.) Simply try again. Perhaps part of the network was momentarily down.
