I'm working on getting a GameLift fleet up and running. I've been testing in GameLift Local for a while now and just recently started using GameLift proper to test the server build. I have it set to be able to handle 10 concurrent processes per instance (with ten ports specified for use), and I only have one instance running. I can connect to the instance just fine with one client, but I cannot connect with additional clients, even though I set it to allow up to ten. Checking the GameSessions tab for the Fleet in the GameLift console, I can see that only one GameSession is ever active at a time. I'm also seeing a bunch of SERVER_PROCESS_CRASHED events in the event tab that say "Server process exited without calling ProcessEnding(), exitCode(0)," and these are happening between every 5 to 10 minutes. I'm assuming the two issues are connected but I'm not sure how to fix it. I've looked for solutions but I haven't found anything that works yet. The game server is built in Unity, and there's a couple of parts of the code that I'm curious might be the issue, even though I never saw any such errors in GameLift local. First, I wonder if I'm calling Application.Quit() to quickly after calling ProcessEnding(). Right now I have them running like this: ``` var result = GameLiftServerAPI.ProcessEnding(); _networkManager.ServerManager.StopConnection(true); Application.Quit(); ``` Based on some other posts I've seen, it sounds like I need to wait until the ProcessEnding() result is true, but shouldn't it already wait to get the result in this context before calling Application.Quit()? Second, I thought it's possible that my method for setting the port might be causing an issue. I had seen a post that said it wasn't working on Linux at one point, but I tested it on a regular Linux EC2 instance in a dummy project with multiple processes running, and they were able to increment through the array of ports I set looking for unused ports. That code is like this: ``` private void SelectAvailablePort() { foreach (var port in ports) { bool available = false; available = IsListeningPortAvailable(port); if (available) { sessionPort = port; break; } } } public bool IsListeningPortAvailable(int port) => !IPGlobalProperties.GetIPGlobalProperties().GetActiveUdpListeners().Any(x => x.Port == port); ``` I'm not sure if this is breaking something on the server, since I was able to get it to work fine in the dummy project on a Linux instance, but since I cannot get past the single GameSession and I remember seeing someone saying it didn't work on Linux, it makes me wonder if it could be the issue. Do you see anything in the code above that could be causing the issue, or if not, is there something else I should try checking to see if it's the source of the problem. Again, I'm just trying to get the game to allow for multiple GameSessions per instance, but only one server process is active at a time. When I try to connect from a second client, I get an error that says there weren't any server processes available. Any advice you may have would be greatly appreciated!lg...

I am using the unity plugin for gamelift, I deployed the first game successfully, but failed when I deployed the second.

Hi community, I was trying to initiate a Gamelift fleet using an zip file from s3 (created by CDK Asset). However the fleet created will get stuck in "Activating" for more than one hour and then error. No usable event log is emitted from console during "Activating". I can ssh into the game server in error status but not sure if that is helpful. Any help would be appreciated on how to debug further. (More context: the server files themselves are fine. I uploaded the zip file directly to create the script and the fleet from the script is created just fine). The s3 access rights seem to be okay too, I followed the example [here ](https://github.com/aws-samples/amazon-gamesparks-integration-with-gamelift/blob/c90c91e78712437c307eed4d7886ae75cda2cfe5/packages/infra/lib/matchmaking-stack.ts). The CDK code for uploading server to s3 and creating the script is as follows) ```Typescript import { Role, PolicyStatement, ServicePrincipal } from "aws-cdk-lib/aws-iam"; import { Asset } from "aws-cdk-lib/aws-s3-assets"; import { Bucket } from "aws-cdk-lib/aws-s3"; import { CfnScript } from "aws-cdk-lib/aws-gamelift"; ... // Upload gamelift real-time server script as cdk asset const scriptAsset = new Asset(this, "MyAsset", { path: pathToScript, }); const assetBucket = Bucket.fromBucketName( this, "ScriptAssetBucket", scriptAsset.s3BucketName ); const scriptAccessRole = new Role(this, "ScriptAccessRole", { assumedBy: new ServicePrincipal("gamelift.amazonaws.com"), }); scriptAccessRole.addToPrincipalPolicy( new PolicyStatement({ actions: ["s3:GetObject", "s3:GetObjectVersion"], resources: [`${assetBucket.bucketArn}/${scriptAsset.s3ObjectKey}`], }) ); const script = new CfnScript(this, "RealTimeScript", { name: `my-script`, version: "0.1", storageLocation: { bucket: scriptAsset.s3BucketName, key: scriptAsset.s3ObjectKey, roleArn: scriptAccessRole.roleArn, }, }); script.node.addDependency(scriptAccessRole); ```lg...

I am working on an Unreal Engine 5 project and want to deploy the game on AWS infrastructure (Gamelift). But came to know that the Gamelift Server SDK and Gamekit doesn't support UE5 as of now. Is there any way around to deploy UE5 game server and backend on AWS or is it like 'if you guys are building on UE5, you have to wait until we roll out an update sometime in the future'? It will be really encouraging if you can share some good documentation/ articles on the topic as well.lg...

I have set up my AWS account and I am integrating fleetIQ in a sample spring boot java project. I have created a Game Server Group named "TestGameServerGroup" and in my backend code I am listing the game server group. After that I am registering Game Server name "game-server-1" in my sample EC2 spring boot project. Now when I update the status of the game server "game-server-1" to "UTILIZED" I cannot change it back to "AVAILABLE". I am trying to update it with SDK and CLI both, but none of it works. The error that I am getting is "An error occurred (InvalidRequestException) when calling the UpdateGameServer operation: Unable to update game server from UTILIZED to AVAILABLE" Command used to set UTILIZED status "aws gamelift update-game-server --game-server-id game-server-1 --utilization-status UTILIZED --health-check HEALTHY --game-server-group-name TestGameServerGroups" Command used to set AVAILABLE status which gives InvalidRequestException. "aws gamelift update-game-server --game-server-id game-server-1 --utilization-status AVAILABLE --health-check HEALTHY --game-server-group-name TestGameServerGroups" Why am I getting this error and can we directly update status to AVAILABLE after setting to UTILIZED? When are we supposed to set these particular statuses? Am I supposed to call any other GameLift FleetIQ API before setting status to AVAILABLE?lg...

Main thing: my own game is about to get finished but theres some bug with matchmaking! my goal is to have more than two matches in one single server just like in any battle royale. also i have a bug where new players keep joining the ongoing game when it already started (and they shouldnt, just like in any br game). When using AWS Matchmaking. AWS will try to fill the amount of players the match is set for. Always. So, we tell AWS to stop back filling players once game has started. Here it’s not listening to our request. Yes, autobackfill its disabled. its manual. Player Sessions get updated everytime a Player Logs in the Game. Its a auto mated process & is called by the server. UpdatePlayerSessionCreationPolicy() << This is C++ function, we have BP which does the same. And, the issue has nothing to do with PlyerSession Update. Any suggestions? Has this ever happened to anyone? I’ll pay if this gets fixedlg...
