Low level fatal error

[lamas09]

I just downloaded Ark but everytime I try to join a server an error pops up:

I´ve been searching how to solve it with no succes, any idea would be apreciated.

Is this an official server join? My first though is that perhaps something has gone a bit pear shaped with your "Battle Eye" installation. If the fail is on official server join, maybe try and uninstall and then reinstall battle eye ...  (Easy test here is to try and join some arbitrary unofficial server that does not require battle eye.)

If not official - I am a little at a loss. Maybe try and verify Ark files? And look at your firewall settings (I am assuming both Steam version and Windows OS). Perhaps your firewall is allowing packets out to Ark, but not OK with letting Ark talk back to you? If that can be the case, then delete and allow re-add of the Ark firewall exception - or manually edit it to allow incoming connections.
