Server Authentication Failed Error "10010"

Hey everyone,

I searched for an answer but the topics I see are since about 20 days ago and I can’t find a working solution. I have the above error popping up since I started the game just now.
I was playing fine during the day but now I can’t enter the game at all.

Any idea how to fix this and a working solution??

Hello @Raltheron,

  4. Force stop Steam

Thank you! Verification of the files worked and I was able to login!
I will see if tomorrow it will behave well again or the error will popup again so I will save those steps just in case.
Appreciate it!

Awesome, glad to hear you are now able to login!

You’re very welcome, see you in Arkesia! :man_mage:
