SBS-3/BaseStation MLAT no need for input data

[phmlr]

I have some SBS-3 receivers running and connected with BaseStation, but i have a problem with mlat-client.exe / mlat-server
(windows: https://radar.lowflyingwales.co.uk/files/windows/LowFlyingWales-mlat-client-Win7-x32-0.2.zip)

A .bat script make its possible to run the software. ( X to hide my location and server info)
mlat-client.exe --user XXXX --lat XX.XX --lon XX.XX --alt 5 --input-host localhost --input-type sbs --input-port 30006 --output-host XXXX --output-port XXX

The receivers are connected to the server and are displaying in the synchronization table with sync to other receivers, but after a few minutes the server drop the connection with "No need for input data" as error.
All of the receivers have a good range so there is always data to calculate.

Assuming the error is "Lost connection to multilateration server, no need for input data".

This is telling you that the TCP connection to the server went down. Either you have a network problem or the server is dropping your connection for some other reason.
