(PC) Battlefield 1 disconnects after ten minutes of gameplay.

Here's what fixed the issue for me.

I'll go in order of priority. For steps 3 and 4, I'm not entirely sure they contributed to the fix, but I'm including them here just in case.

1. Redownload EA anticheat to make sure you got the latest version. Installation details are in the link
2. Allowing EA Anticheat and Javelin to your firewall
   1. Go to Windows Control Panel and check "Control Panel\All Control Panel Items\Windows Defender Firewall\Allowed apps"
   2. Hit Change settings and Allow another app 
   3. Hit Browse and add EAAntiCheat.GameServiceLauncher.exe    C:\Program Files (x86)\Steam\steamapps\common\Battlefield 1\EAAntiCheat.GameServiceLauncher.exe
   4. Add EAAntiCheat.GameService.exe located in     C:\Program Files\EA\AC\EAAntiCheat.GameService.exe
   5. Now, tick the boxes that say Name, Private, and Public for EA Anticheat and EA Javelin Anticheat
3. Give both Anticheat executables admin permission
   1. Navigate to C:\Program Files (x86)\Steam\steamapps\common\Battlefield 1\EAAntiCheat.GameServiceLauncher.exe
   2. Right-click the EAAntiCheat.GameServiceLauncher.exe and hit properties
   3. Under Compatibility, tick the box that says "Run this program as an administrator"
   4. Do the same steps to EAAntiCheat.GameService.exe located at   C:\Program Files\EA\AC\EAAntiCheat.GameService.exe
4. Re-enable DNS Client if the process is switched off
   1. You can follow this step-by-step tutorial here and use the Automatic option for DNS Client   
   2. Basically it's just going into cmd as an admin and entering     REG add "HKLM\SYSTEM\CurrentControlSet\services\dnscache" /v Start /t REG_DWORD /d 2 /f

Hope that helps 👍
