Yo, dunno if i’m the only one but started to get the EAC offline error… Yesterday i played without any issues but since this morning the error came up, i tried playing in NA EST and the error didn’t show up so dunno what should i do?
Hi @Flaggyx.
Welcome to the Lost Ark forums, hope you’re good 
I’m sorry you’re getting his error with the EAC that prevents you playing Lost Ark, let’s fix that quick, can you try this first please:
Try adding Windows firewall exceptions manually:
Press Windows + R, type “firewall.cpl” into the Run window, and then press Enter.
Click Allow an app or feature through Windows Firewall and then click Change settings.
Look for the game in the list of allowed apps and features. If it’s present, make sure it’s checked, and that both the Private and Public columns have a check mark. If the game is missing from the list, you must add it.
Click Allow another app…, locate and select LostArkLauncher.exe, and then click Add.
Once you’ve done that, make sure that Lost Ark has check marks under both the Private and Public columns.
If the issue persists, here’s some more stuff we can try:
