Apex Legends Steam — Javelin AntiCheat error [4]

Thanks for the detailed report and for listing everything you’ve already tried.

Since the Event Viewer is showing "Failed retrieving service path", could you please try launching the EA app as Administrator and then launching Apex Legends directly through the EA app, even though you normally play through Steam?

If that doesn’t make any difference and you don’t mind trying one more step, it may also be worth reinstalling Apex Legends to its default installation location and testing again.

Please let us know whether either of these changes the error or allows the game to launch.

this solution wont work i tried all of them Running both Apex and EA as Administrator and reinstalling the game. i have the same problem sofar no solution. 

Thanks for the suggestions! I already tried running EA and Apex as administrator, and I also tried reinstalling the game, but neither worked for me. What finally worked was disabling IPv6 in my Wi-Fi adapter properties. Apex stopped showing the Javelin AntiCheat error [4] on my Verizon Wi-Fi after that. Hopefully this helps others with the same issue!

Thanks for sharing!

Please try the solution shared by zKm_03​ , which involves disabling IPv6 in your Wi-Fi adapter properties, and let me know if it helps.

Thanks!

so finally i fixed the issue. i went through all windows services one by one enabling them and lunching apex and try if it was fixed. so the service which was disabled for me was DNS client by default its on on windows but i did some tweaking to my OS so it was disabled. now i enable it and i dont get kicked from matches and no anti cheat Error. This was not happening with EZ anti cheat but seems like javelin anti cheat needs DNS Client service to be running. pls share this fix because i had seen a lot of posts where they suffer the same issue.

Thank you very much
