We have observed, that when a LAN TCP/IP connection is established between a Neets control system and a 3rd party LAN device and the connection is for some reason dropped, then it is not able to detect this drop and re-establish the connection. Examples of dropping the connection could be an unplugged cable or loosing power on a network switch etc.
If the 3rd party device or the Neets control system closes the connection instead, then the connection is re-established correctly.
We have seen this happen on SieRRa II, TanGo, LiMa and AlFa II running firmware 3.27.1, but other control systems, might be affected as well.
Restart Neets control system
