      Hi,

      I’ve got something strange. I have been flying a while offline only and I wanted to restart multiplayer activities.

      When I launched my BMS, I was connecting to a server (2048 download & 1024 upload, something I used all the time).
      I successfully connected, IVC was launched, BMS was up, I saw the other players on the server and all of a sudden BMS shuts down. No error msg, nothing.

      After a reboot, I tried again and now BMS just closes when I connect to a server.
      Network wise all looks good (incl ports). Except a standard windows firewall, I got no other security apps. I added the complete Falcon folder to the exceptions and already added all Falcon exe’s to the firewall exception list. Just to test I also deactivated firewalls but no luck.

      So in short; it worked a few seconds but it’s now by default shutting down BMS when I connect. In offline mode all OK.

      Any ideas?

      Kind regards

        @PopTops In my experience those bandwidth numbers that you put in seem a bit small. You could check the servers instructions if they require some other numbers

          To be fair, connection with less than 2048 on upload are very unstable…

          Tested in multiple mass events… Slow and unstable uploads are a real problem we can’t solve easily…

            @PopTops please provide DMPs so we can debug this.

              @PopTops 2048/1024 are old standards, I suggest you review 6-75 in the BMS User manual:

              Here are guidelines on how to input Bandwidth settings:
              o Each client (as well as the server) should pick his/her own personal setting, the clients do not need to match up.
              o Each individual download and upload rate should be roughly 80-90% of your measured internet connection speed. Why 80-90%? You may need spare bandwidth for IVC or TeamSpeak, or someone else using up bandwidth watching IP TV or whatever; only you know how much spare bandwidth you’d like to reserve.

                I will try adapting the bandwith flow and report back. If still occuring I will look for a crashdump.
                Note I always used 2048 and 1024 (stable on my side since ages 😉 ). But of course in IT-world it doesn’t mean anything, maybe with 4.36 these legacy parameters are simply not usable.

                  @PopTops did you by any chance overwrote the Falcon BMS.cfg from 4.36 using the one from 4.35?

                    Not sure anymore but it could be replacing it with my previous user files.

                      Hi, just so say the problem has been solved. Solution:

                      • Delete 4.35 files that were still alongside (so @Seifer , you might have been correct pointing to a version conflict of the cfg file)
                      • Update to 4.36.1

                      Thanks all!

                        Curious, how can any files from 4.35 be “alongside”? 4.35 and 4.36 are totally independent installations and can coexist quite well…
