Found a fix while going through serveral comments and trying serveral things, although I think the fix has worked I haven’t given it a huge amount of time but considering I would get kicked off every ten minutes or so I think it’s a massive improvement.
All of this is shamelessly stolen but I can’t find the exact comments rn, one of them was from a mod but I don’t know how much his suggestion actually helped but I’d try it anyway.
Validate your Lost ark files in steam, right click lost ark, go to properties, local files, then verify the steam files for lost ark.
Next, check your easy anticheat is working, I found mine by going to, steam, right clicking lost ark, manage, browse local files, and searching easy in the lost ark folder, run EasyAntiCheat_Setup and either install or repair.
Next I installed TCP optimiser, I ran the optimal settings at a mbp above my usual speed.
I then turned off my firewall but you can try making sure both lost ark and steam are being allowed through on private and public.
After you’ve done all this you will need to reboot your pc (at least to take in effect the TCP optimiser settings)
I don’t know if this will work for everyone but it’s working for me so far. Again I know this isn’t a user side error but I fixed it myself despite the fact that it’s definitely a problem that’s come through the recent update, (at least for me)
Edit; I recently did a full drivers update ranging from Network drivers to gpu drivers, I don’t know how much this effected it but just thought I’d mention it. But since I still ran into the problem after updating everything I wouldn’t tie them together yet.
This all worked for me but I’ll update if it doesn’t work for extended amounts of time, since I haven’t given it a long enough test. This is still on Smilegate to solve as they are going to see a steady decrease in players sooner or later as this begins to happen to more players.
