Sometimes, the OneDrive application can access your game files and try to read or write them during gameplay.

For this:

  1. Press “Windows + R” to start the Run prompt.

Solution 6: Connect Using LAN

If you are using a Wi-Fi connection, you should try to switch to a LAN. This helps in ensuring maximum network stability as a lot of electronic equipment can interfere with your Wi-Fi signals. Also, it helps in maintaining a more secure connection. Thus, we recommend that you try to switch to a LAN and check if it helps in connecting to the DayZ server normally.

Solution 7: Don’t Use USB Tethering on Mobile Hotspot

If you are using your mobile’s hotspot via USB tethering, you shouldn’t. This is because certain security protocols can be triggered when you do this that can prevent your connection. Thus, you can try to use a Wi-Fi hotspot instead and see if that works out better.

Solution 8: Use a Workaround

Some users explained that if they press “Alt + Enter” when they get the Car UI, the game works and connects fine for them. Thus, you can try to do the same. They also told us that you are still getting the error after doing this, try to wait for a couple of minutes and then try again.

Solution 9: Use Another Workaround

Another workaround that worked for some users was to launch the “DZSA” launcher. After that, you can try to load the server after choosing it. Now, when the “Character” screen shows, you should select the “Change Server” option and then utilize the “Search” function to find your server. From there, select “Play” and it should allow you to connect to the DayZ server normally. Check to see if this helps in fixing the Dayz 0x00010001 Error on your device.
