Same issue here for 3 days straight. Tried every troubleshoot out on the internet but no luck.I have never used VPN also.
Just tried the things you suggested, sadly it didnt help
I’m having the same issue. I don’t and never have used a VPN for Lost Ark and since the block, I’ve not been able to log into the game using my normal home internet.
I also tried all of the previous recommended fixes and reached out to my ISP several times this weekend to confirm they’re not using a VPN tunnel. I tried your recommendation now but it didn’t work. I continue to get error 10010.
Thank you for at least posting something different to try!
Same issue here, from my office network now I am not able to play. I have no issues from home.
Hola, primera vez que me pasa esto llevo como 2 h intentando entrar he echo todo lo que decíais y sinceramente no va, tengo 7 alters y no veo solución salvo dejar el juego sobre todo viendo que tiene como un año este post y no se a solucionado.

Same here…cant log in. Disabled IPV6 , validating game files right now. I was playing a few hours ago. This is bad because my guild is starting our runs , well, basically now
Is the game broken, guys? Or is it just me??? After today’s patch, i can’t even get past the loading logo, and when i manage to do so, it crashes right after the character selection… It keeps crashing all day for me today…
Missing my Brel static run thanks to this! 
I was playing this afternoon just fine. But now I keep getting this error while trying to load the game.
Can you confurm its after a steam update?
Yes i ‘confirm’ it is after the steam update sir.
I played last night and hadn’t opened the game, or even Steam, until I got off work today and I’m currently having the same Server Authentication issue as others. The game updated ~50 minutes ago, automatically, when I first opened Steam today and I’ve not been able to reach the server select screen.
