Hi, Why I can not open Lapper 2 grain ?

By the looks of it, the insim port(s) aren't opened on the LFS server(s) or they both use the same port number.
There also seems to be an issue with the password being used, which prevents Lapper from connecting to your LFS server.

Thank You Yisc[NL]

Good to see it's working.
But you don't need to run Lapper twice.
It's possible to run multiple servers while only running Lapper once.
Search for this file: LFSServers.cfg

Then set something like this:

Server1|gr1|127.0.0.1|29998|./default|server1.ini|autoWork
Server2|gr1|127.0.0.1|29999|./default|server2.ini|autoWork

Of course you need to create a seperate ini for each server.
So make copies of "default_1.ini" rename them to "server1.ini" and "server2.ini"
Then adjust those ini-files so that they have the correct password for their corresponding server.
Create seperate "LFSLapper.lpr" if servers need a different configuration.
If not, then you can leave that as it is.
