my L2net always disconnected

i downloaded and started the bot (in this case L2Net)

the bot is working fine, it can kill the mob, pick up the items

so, all the configs went good, then something happen,
everytime 5 minutes or less i got this messages :


13:23:39 :[ERROR: crash: GameSendThread : Unable to write data to the transport connection: An existing connection was forcibly closed by the remote host.

:[ERROR: crash: GameSendThread : Unable to write data to the transport connection: An existing connection was forcibly closed by the remote host.

then the bot disconnected from the server

info : i play L2 in retail server / official server (indonesia)

i hope for the solution, thx in advance (sorry 4 the bad english )

try to ask on the l2net official forums,dont know how i could help u with this one
