Lost Ark Server Authentication Failed 10010 Explained

If you can't log into Lost Ark servers due to Authentication Failed 10010 error message, here's what it means and how you could potentially fix it.

Lost Ark has been one of the most popular and consistent MMORPGs for many years. But recently, it seems bots have been making things insufferable, resulting in errors and other various bugs. One that many players have run into is the 10010 server authentication failed log-in error. If you're here, you're wondering if there's a fix. We explain below.

What is Server Authentication Failed 10010?

Amazon Games, the publisher of Lost Ark, has banned all connections to the game that are heavily exploited by bots via VPN services. That is the main reason why players who use VPN services to play Lost Ark receive the 10010 error message and cannot log into the game servers. You can read the official statement on the Lost Ark forums.

Potential Fixes for Lost Ark Error 10010

If you are using a VPN, first try turning off your VPN software and connecting to Lost Ark via a normal connection. If you still can't connect, then check out the Lost Ark servers status page to see if the servers aren't overpopulated at the moment.

It is possible that you could run into this authentication error without running a VPN, as well – or you may find that turning off your VPN doesn't work. In that case, there are a few tried and true options try: 

  • Log out of Steam and log back in.
  • Verify the integrity of your Lost Ark game files.
  • Restart your computer and log back in. 
  • Restart your modem/router.
  • Switch to a wired connection if possible. 
  • Set TPS Protocol to 1.2.
  • Clear your DNS cache or change DNS servers.

If all else fails, then you could call your ISP and ask the provider to turn off their VPN if they are running one, though that is likely to be a futile endeavor.
