Hello,

One of the players on my server keeps getting disconnected after 20 minutes to an hour of play.

6 months ago they played on one of my servers, same map and mods and had no issues. They are using the same computer now.

Any suggestions would be great So far he has Rebooted Updated all drivers Validated Files of Ark Uninstalled Ark and reinstalled Ark Remove all steam MODS for Ark Reinstalled all Steam Mods Searched the inventory for a solution

This is the Error Message he receives.

I would recommend checking on the official ARK forums for that, as it's an actual ARK error, and not something host related. But looking over it, there's a lot of memory addresses mentioned in the debug output, which could indicate some type of machine hardware issue. Typically some type of writeable media with a bad sector can throw those.
