Do you have a server_log.txt file for that? This error code is created from having some malformed parameters that the server is trying to list itself as on the server browser. Things like a missing server name, session, intent.

You are right I did find text files named server_chat_log.txt and server_log.txt in the Master and Caves of the server folder, where the description in server_log.txt is the same as my error report What should I do to fix it?
