EAC authentication failed after update.

[Arsonist]

Is anyone else having EAC issues suddenly? Game server keeps rejecting my connection but only allows me on if I disable EAC server side and then everything works fine. I run the file validation check through steam and it comes up with no modified files found. This wasnt happening yesterday.

With EAC enabled on the server, the kick message I get is "Authentication failed. EAC sandbox not active( dummy client )." Wtf does that mean? So vague

Have you tried a soft--for lack of better way to describe it--uninstall of the game and re-install through steam? I don't mean a "Clean" uninstall where you manually delete the 7d2d folders that get left behind... just standard one where you let steam do the work and leave it at that. This sometimes fixes issues without you losing save data. Your .xml's will get reset to default though, and you would need to alter those again if you had to begine with.

In your 7 days to die folder there is a EAC.exe. You can try running that and see if that solves your problem.

I have EAC enabled in game launcher but seems like its failing to start or crash when the game runs. My game is running but EAC isnt listing in windows task manager. EAC wasnt failing until today. Im aware it be started manually in game folder but shouldnt have to

It is a manual install, you have to open EAC then choosee 7DTD from the drop down & install. It does not install on any updates or reinstalls you have to do it.

Umm.. no. Its not a manual install. Downloading the game via steam is the only thing I have to do. EAC comes with the game. Setup and updates are automatic by default.

Turns out the problem was the application rules in my firewall got wiped and EAC ports blocked. Re-added the game and EAC in the firewall rules and it started working again. This normally doesnt happen.

Its happened to me a couple times...I just closed 7d2d and opened it and tried to relog. Usually took more than 1 try but it worked.

hey .... i´m having same problem with the EAC and i found the EAC directory inside the game ... there is a exe file that let you fix EAC or install it again but doesn't work for me ...

[jjcm2002]

anyone still has this proble still ?

[Felix]

I do have the problem. It even kicked me out of a game, telling me I couldn't connect to any EAC protected server during this session. I reinstalled the game, rebooted my PC, reinstalled EAC...
It worked randomly, just by trying over and over again. Then rinse and repeat cause it happens every time

I am I also having this problem. Here is what my launcher log file says:

I had this same problem and tried many things: re-installing the game, re-installing EAC, I ran the EAC "repair" service, disabling my firewall, disabling my anti-virus but none of these things worked.

I discovered that an EAC file that should exist didn't. The file is "%AppData%\Roaming\EasyAntiCheat\17\easyanticheat_wow64_x64.eac" and it was simply missing. A friend sent me his via email, I copied it in place and EAC started working again. Why the "repair" and re-install didn't replace this file I do not know. Seems like a bug.

If you have a mac you have to wait for an update to EAC, after a mac update. I do nto have a mac nor do I bother to try understand them though so beyond that ask a mac savvy person any questions about it.

If you do not have a mac just delete EAC and reinstall it.
