    Sat Dec 16 17:43:14 2017 Receiver:  552.0 msg/s received       81.0 msg/s processed (15%)
    Sat Dec 16 17:43:14 2017 Server:      0.0 kB/s from server    1.2kB/s TCP to server     0.0kB/s UDP to server

    Sat Dec 16 17:43:14 2017 Aircraft: 6 of 6 Mode S, 29 of 30 ADS-B used
    
    Data is now taken directly from dump1090 - the only thing I had to change was the input type from auto or anything else to dump1090 - looks like dump1090 is the only working option. I will now go ahead and try to get it working via a vrs feeed ... many thanks for your help!

    Viva le MLAT!

    I briefly looked at the code on github for the client / server and I don't see where the username is important for anything but identifying a mlat-client so a server operator can give support.

    Just FYI, it stopped working again ~90min ago.

    You're still on sync matrix. What is the problem?

    Same problem like recently, only affecting MLAT.
    Connection to the server is just kept for a few seconds (probably exchanging key information - thus I'm still on the matrix), then connection gets lost - repeat every 30 or so seconds.

    Probably load balancing... But you're still present on sync-matrix. Let admins look at this issue.

    Do you know if they have monitoring for this kind of stuff or is there a recommended way to inform them?

    When one of the MLAT servers CPU's is spiked at 100%, sometimes a server won't accept connections or will drop connections. It usually a short term issue. and gets load balanced out. We do montior them them but I need to work on improving the whole shabang! $ and time.
