Fleet not activating - Game crash without error

I don’t know why my fleet is not activating. I’m running an Unreal Server on Linux with a simple code for GameLift. The ProcessEnding method is called when a ProcessTerminate action if triggered from Gamelift, but when the fleet is activating, the process crashes with an event on fleet: SERVER_PROCESS_CRASHED

Server process exited without calling ProcessEnding(), exitCode(1), launchPath(/local/game/GalacticDefenders/Binaries/Linux/GalacticDefendersServer), arguments(-port=7777)…

When I’m checking the game server logs, the following can be seen:
[2021.06.17-14.27.03:527][456]LogCore: Engine exit requested (reason: EngineExit() was called; note: exit was already requested)

[2021.06.17-14.27.03:952][456]LogCore: FUnixPlatformMisc::RequestExit(bForce=false, ReturnCode=130)

The error code 130 is a SIGINT, it means a Crtl-C on the process basically.

So, why the fleet is stopping with an interruption the process?

My fleet id is: fleet-e84ea859-29f0-4407-9575-d3791c7aed93


Forget about it! the logs I see wasn’t from server but for my local tryouts. The error is about GLIBC_2.29. Apparently I’ve build SDK with wrong Ubuntu version. Trying out with other Ubuntu version.
