Can't Connect to Online Server

[cwhite11]

Kicked from server: EAC violation: ClientAuthenticationFailed - EAC sandbox not active (dummy client) is the error I get when trying to join any server. I have tried reinstalling EAC and running the game as admin. I don't see a way to attach a log, so I will paste it below (sorry).

I'd start with verifying your game files twice.

[meganoth]

Use pastebin or similar for posting logs, this is explained in a pinned thread here in the forum. Can you start a local EAC-enabled game?

 

[cwhite11]

I can start a local game and have had people join me successfully, I don't see where I activate EAC for the local server or not in the options but the times I have played locally I have always used the EAC launcher. I only see this error when I try to join the public servers. Acknowledged on using pastebin, my bad on that. I can try anything that is suggested.

[Star69]

As was mentioned earlier, verify game files twice. Also, be sure you have excluded the game and eac(I personnally exclude the entire Steam folder) from your antivirus program. Make sure you have fully allowed eac and 7Days through your firewall. Finally, shut down Steam and reboot your computer and restart Steam.

[cwhite11]

I have completed those steps and the problem is persisting. One file was replaced when verifying the files, but didn't seem to fix the problem. Both EAC and 7 Days are allowed through my firewall.

[meganoth]

EAC is enabled (or disabled) in the launcher, there is a checkbox for that. 

 

There is also a tools-tab in the launcher where you can delete game settings, data imported from other servers, ...

Backup all data you still want to use in the future (local savegames and saved world data) and then preferably delete everything (i.e. check all boxes)

 

 

[Star69]

From a developer of EAC posted to Steam forums concerning this exact error but another game: Anti cheat EAC sandbox not active (dummy client) :: Hell Let Loose Report a Problem (steamcommunity.com)

 

So replace the other game's name with 7 Days and hopefully will solve your issue
