Why do you get the Bios Error 0x00050009 DayZ?

After being stumped by this issue, a lot of users came to us for guidance. From our investigations, the most probable causes for the error 0x00050009 are as follows.

  • General Glitch: Most users who have seen this error get it because of a glitch with the game. It came after an update from the developers and has been prevalent ever since. As said before, it is due to a bug with the “favorite” feature that the game has. The feature allows you to add some servers to your favorites.
  • Missing Permissions: Sometimes, the game might be missing important permissions that it requires. This can range from permissions that it needs to use the internet or to receive network bytes. Thus, a simple fix is to provide it with the necessary permissions as we have done below.
  • Glitched Start: If the console that you are trying to play on doesn’t start properly, you can get the Bios Error 0x00050009 DayZ. Thus, you should try to employ the age-old method of turning it off and then turning it back on again.
  • Game Files Validation: If important game files are missing or corrupt, you might run into this issue. Thus, we suggest that you try to validate your game files and check if they are intact. We have demonstrated the steps to do so below.
  • Server Issue: DayZ often comes across server issues every now and then. If you are getting the error, you need to make sure that it isn’t DayZ servers that are down right now. To check this, there are several sites that you can check, some of which we list in the solutions below.
  • Security Block: Some users might have the security block on a DayZ-related service in their router’s firewall. If this is the case, your router won’t allow the network bytes from DayZ servers through the firewall. This, in turn, can end up causing the Bios Error 0x00050009 DayZ.
