So, I recently started running a new bukkit server off my home computer. I've set one up before, and everything runs correctly, and all the plugins I've installed work fine. I'm using the 1.0.1-R1 release, and I've downgraded my Minecraft client to version 1.0.0 using MCNostalgia. The downgrade went sucessfully, and now the only thing I've done to the client was run MCPatcher to get my texture pack working properly. The first time I try and connect to my server, everything goes as it should and I can connect and play on the server. However, if I disconnect from the server, and then try and reconnect, I'm greeted with the following message (in the client): Code: Connection Lost Failed to login: Bad login The only thing the server says is Code: /XXX.XXX.XXX.XXX:XXXXX lost connection When I go back to the title screen, and try and go back into the multiplayer menu, the server usually says that there's a communication error. The only way I can get back into the server is by restarting the Minecraft client.
