A3 Launcher will not let users in on first attempt



  • We own a server and many of us are having the same issue. A3 Launcher will not work on the first attempt to join the server... it just freezes at the loading screen of the server. If we join through the regular Arma Browser, exit out and try again with A3 launcher, it seems to work. Were concerned that we're losing potential new players especially because we're a promoted server.

    Any thoughts?



  • I ran tshark and filtered on my friends IP that was having an issue getting into the server. Keep in mind, there are zero logs being outputted on client side or server side. I had to launch tshark to even see if his computer is attempting to make a connection. I also disabled all firewalls on both sides and we still seem to have the issue. Since we are paying to be sponsored, we hope to get some help on this.

    Here is the first attempt that failed:

    Now after he closes Arma and restarts A3Launcher, he was able to connect and join:

  • We also noticed this file logging an error output.log under the A3Launcher folder:

    17.01.2017 14:24: Info [line: 0 MissionPrefetcher -> Fetch()]: Starting mission prefetch
    17.01.2017 14:24: Error [line: 0 MissionPrefetcher -> Fetch()]: Log exception -> Message: One or more errors occurred.

    Possible issues with getting the mission file?



  • He turned off prefetch mission file and the exception went away but he still wasn't able to connect to the server. Only after he connects using Arma 3 Launcher, he can then use A3Launcher to connect.
