Thank you so much for reporting this EAC disconnection’s errors. I also want to thank you for sharing the troubleshooting you’ve done so far.
The next troubleshooting I want to verify with you if the related with the Windows Firewall settings and Internet Protocol Version 6 (tcp/ipv6):
Troubleshoot your firewall.
-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 app is missing from the list, you need to add it.
*Click Allow another app…, locate and select the app, then click Add.
*Once you’ve done that, you need to ensure that the app is checked, and that it has check marks under both the Private and Public columns.
Disable your IPv6:
Open Windows settings.
Go to your Network&Internet section.
Click Change Adapter Settings.
Right-click your connection (It can be either LAN or WIFI adapter) and go to Properties.
Scroll down in the menu until you found the option Internet Protocol Version 6 (TCP/IPv6)
Uncheck the box next to it and restart your computer.
After this process verify Steam Integrity Check files:
Re-launch Lost Ark.
Please let us know if the problem keeps persisting, I’ll pending of any update you want to share. ฅ^•ﻌ•^ฅ
Hey, thanks for the tips. I did all of that and I still got a disconnect (Cannot connect to the server. [EAC Offline]). We’ll see if they’ll be as often as the past weeks though - so far one DC in around 1 hour.
I want to apologize for my delay, I was off-shift. Thank you so much for keeping your post update for this issue. If the issue keeps happening, I’d to ask you to please submit a web ticket directly to the Dev’s team using the link below:
