The release of the latest game in the Arma franchise has seen players eager to play it, with the unfortunate result of many of them experiencing the Arma Reforger session error. The error is preventing those players from getting into the game, thwarting their hopes and dreams, and condemning them to a lifetime of bitter regret. Or at least until the issue is fixed.

In an attempt to make that regret last as briefly as possible, we’ve assembled a guide to help explain what this error is, and what you can do to try and fix it. You’ll finally be able to sample the delights of Arma Reforger.

How To Fix The “Connection Has Failed” Error

Unlike many errors, this particular issue has one very clear cause (more on that below) and therefore, one very clear solution. Usually, the most effective way to remedy this issue is to try joining a server which doesn’t have a lot of traffic.

To do this, start by looking for servers which have a low number of participants. Sometimes there is a lag between players joining a server and the player count being updated. So you might find you try to join a low-count server, only to be told you can’t access it. If that happens, try another server, until you find one you can join.

Alternatively, you can try setting up a Game Master match, and create your own map as other players join. You can also just leave it for a while, and try going back to the game at a time when you’d expect it to be quieter.

If these options don’t work, then another way of trying to find quieter servers is through using a VPN. As this will change the location from which the servers think you are located, it may link you to a quieter server than the one in your local area.

Finally, it’s always worth making sure that there are no connection issues at your end. So test a different game or app, run a speed test, and consider using an ethernet cable if you’ve been on WiFi. We’d also recommend that you try to minimise the amount of traffic on your own network.

If nothing is working, check that your system meets the minimum requirements for the game. If it does not, then no amount of troubleshooting is going to prevent you from running into trouble. The minimum specs are:

  • Requires a 64-bit processor and operating system
  • OS: Windows 10 64-bit
  • Processor: Intel Core i5-4460 / AMD FX-4300
  • Memory: 8 GB RAM
  • Graphics: NVIDIA GeForce GTX 1650 or similar
  • DirectX: Version 12
  • Network: Broadband Internet connection
  • Storage: 15 GB available space
  • Sound Card: DirectX®-compatible
  • Additional Notes: Internet connection and DirectX 12 compatible PC required.

What Is The Arma Reforger Session Error?

As anyone who has experienced this error will already be aware, the session error arises when players are trying to join the server and enter the loading screen. They then receive a message which says, “Session error, connection has failed”. At this point, they are unable to join the server and start playing a game.

The error itself seems to be triggered by the servers being unable to cope with the volume of traffic. Which is understandable. New games always tend to see a significant spike in traffic as people are eager to try them out. Add to this the fact that Arma Reforger is still in early access, and you can understand why this could be a problem.

Early access essentially means that the game is not finished, so it is highly likely that the servers aren’t equipped to cope with everyone trying to get online.

At the moment, the servers don’t have a huge capacity, so the error is much more likely to occur if you are trying to join one that is already nearly full.

So try the advice we’ve offered above, and hopefully, you’ll quickly find a server that can grant you access. And as time goes by, we’d expect traffic to stabilise, and server capacity to grow. Both of these things should then reduce the prevalence of the Arma Reforger session error.
