You disconnect because the connection times out:
Leaving GameConnection::onConnectionTimedOut() - return
And I think it happens because of a chat addon:
Entering clientCmdServerMessage(88 MsgClientKilled, 64 <bitmap:base/client/ui/ci/skull> mokeytonic2001, mokeytonic2001, mokeytonic2001)
Entering defaultMessageCallback(88 MsgClientKilled, 64 <bitmap:base/client/ui/ci/skull> mokeytonic2001, mokeytonic2001, mokeytonic2001, , , , , , , , )
Entering onServerMessage(<bitmap:base/client/ui/ci/skull> mokeytonic2001)
Entering newChatHud_AddLine(<bitmap:base/client/ui/ci/skull> mokeytonic2001)
Entering NewChatSO::addLine(10397, <bitmap:base/client/ui/ci/skull> mokeytonic2001)
Entering NewChatSO::displayPage(10397)
Leaving NewChatSO::displayPage() - return
Leaving NewChatSO::addLine() - return
Entering newMessageHud::updatePosition(newMessageHud)
Leaving newMessageHud::updatePosition() - return
Entering newChatHud_UpdateScrollDownIndicator()
Entering newChatHud_UpdateIndicatorPosition()
Leaving newChatHud_UpdateIndicatorPosition() - return
Leaving newChatHud_UpdateScrollDownIndicator() - return
Leaving newChatHud_AddLine() - return
Leaving onServerMessage() - return
Leaving defaultMessageCallback() - return
Leaving clientCmdServerMessage() - return
Entering GameConnection::setLagIcon(68627, true)
Leaving GameConnection::setLagIcon() - return
Connection to server timed out
Entering GameConnection::onConnectionTimedOut(68627)
You have any of those by any chance?
