Hi, i'm trying to start a local build as multiplay server but i get this error

#

by local build i mean a server build on my pc

outer flume Feb 1, 2024, 4:30 PM

#

Server build is working when loaded on the Unity dashboard for game server hosting

I managed to write the correct json:

{
"allocatedUUID": "434af841-586d-4403-939b-db19f77611a6",
"serverID": "12345",
"queryType": "sqp",
"queryPort": "9010",
"ip": "127.0.0.1",
"port": "9000",
"serverLogDir": "12345/logs/"
}

but i get the error:

07/02/2024 16:18:16|Fatal|ThreadPoolWorkQueue.Dispatch|Connection refused
[Wire]: Websocket closed with code: WebsocketAbnormal
UnityEngine.Logger:Log(String, Object)

Can be the that i'm using the ApiCreateServerClient and it doesn't like it?

#

BTW the correct Json that i'm using is different from your Json in the docs, so i think your doc is wrong

#

The error seems to come from wire which should be unrelated to the Api package's functionality.

I'm not sure what you are trying to do exactly locally though. You can't mimic a multiplay server locally

#

Sorry for the delays, it's a crazy day

unkempt garnet The error seems to come from wire which should be unrelated to the Api package's...

I'm trying to start a local server as i was doing with playfab, but if it is not possible or overcomplicated i can just load builds on multiplay and test; Don't worry for the delays, i understand.

unkempt garnet Feb 7, 2024, 6:16 PM

#

For a local server, I think the only option right now is to connect your clients to it directly with ip/port. The local server won't be able to mimic all functionality of a multiplay server but some of it should be possible.

Do you have a bit more details on exactly what your server is trying to do?

outer flume Feb 7, 2024, 6:56 PM

#

That's exactly what i'm trying to do, but if the server doesn't start properly...😄, here it is my server logic

At the moment my priority is to make it works on the unity multiplay service, and it works, but as you can see i have some issues in local.
There is one thing that make my builds don't work on multiplay service, when after the allocation is made i call MultiplayService.Instance.GetPayloadAllocationFromJsonAs, at this point the serivce gives me this error HttpException: (404) HTTP/1.1 404 Not Found

#

To be clear, it works on multiplay service when i omit the GetPayloadAllocationFromJsonAs

unkempt garnet Feb 7, 2024, 7:07 PM

#

The MultiplayService is really only made to work when running on a Multiplay server. I'm not sure it's possible to make it work locally.

You could consider having a conditional macro for that part of the code for when you are on multiplay or local, or try catch it knowing it will fail on local.

I'm not sure if there's any part of that functionality that you do need to do for your local one.
It's a workflow we want to improve so i'm curious to learn a bit more

ok got it, now..., looking at when the builds is running on Multiplay server, can you help me understrand why is giving me the "HttpException: (404) HTTP/1.1 404 Not Found" when calling "MultiplayService.Instance.GetPayloadAllocationFromJsonAs" after the build is allocated?

unkempt garnet Feb 7, 2024, 7:18 PM

#

Is this a test allocation?

outer flume Feb 7, 2024, 7:19 PM

#

oh yes... but i can try with the matchmaking

unkempt garnet Feb 7, 2024, 7:20 PM

#

I've seen a forum post that mentioned that as a cause, though i'm not 100% sure if that's the reason

outer flume Feb 7, 2024, 7:20 PM

#

i'm trying with the matchmaking right now

#

The matchmaker is not matching my two build instances with different accounts (NOT ANONYMOUS SIGN IN), is caused by the fact that i'm on the same PC?

#

because with a ticket with one player needed it was working

unkempt garnet Feb 7, 2024, 7:44 PM

#

On the same pc, you need to use authentication profiles to have different players

#

oh wait

#

it should work if you have different accounts

#

Your ticket shoudl have 2 players or more

outer flume Feb 7, 2024, 7:46 PM

#

unkempt garnet Your ticket shoudl have 2 players or more

Yes i know, look at that

unkempt garnet Feb 7, 2024, 7:46 PM

#

Looks fine

outer flume Feb 7, 2024, 7:46 PM

#

unkempt garnet On the same pc, you need to use authentication profiles to have different player...

i'm using two different game accounts logged by sign in with username and password

#

if i use the ticket setted with the maximum player to one, it works

#

only with one player obviously

#

i'm trying to copy the project on another PC

unkempt garnet Feb 7, 2024, 7:50 PM

#

I do matchmaking on the same pc all the time, it should not be an issue. You can always verify the player ids, project ids and ensure everything is right

Are you using multiplayer play mode (or parrelsync)?

outer flume Feb 7, 2024, 7:52 PM

#

I'm using Parralelsync

unkempt garnet Feb 7, 2024, 7:53 PM

#

How is your pool configured

outer flume Feb 7, 2024, 7:54 PM

#

#

I can see my tickets here

unkempt garnet Feb 7, 2024, 8:28 PM

#

Can you let us know your project id?

#

maybe in DM

outer flume Feb 7, 2024, 8:32 PM

#

unkempt garnet Can you let us know your project id?

Done in DM

Hi there, I work on the matchmaker here at Unity, this looks pretty straightforward and I don't see anything wrong with the configuration of the matchmaker. I'll take a look quickly on our side see if I can see anything wrong with the ticket we are receiving

outer flume Feb 7, 2024, 8:33 PM

#

thank you guys, much appreciated

sleek cobalt Feb 7, 2024, 8:38 PM

#

so from our point of view, it seems like the tickets are sent with the same playerid in the ticket, but the author are differents.

outer flume Feb 7, 2024, 8:39 PM

#

sleek cobalt so from our point of view, it seems like the tickets are sent with the same play...

how is that possible?

sleek cobalt Feb 7, 2024, 8:39 PM

#

Ticket 1:

outer flume Feb 7, 2024, 8:39 PM

#

what is the difference between the author and the player?

sleek cobalt Feb 7, 2024, 8:39 PM

#

Ticket 2

unkempt garnet Feb 7, 2024, 8:40 PM

#

Oh what are you putting in MatchmakerService.Instance.CreateTicketAsync

sleek cobalt Feb 7, 2024, 8:40 PM

#

we allow for players to include others players than just them to support for party matchmaking

outer flume Feb 7, 2024, 8:41 PM

#

unkempt garnet Oh what are you putting in MatchmakerService.Instance.CreateTicketAsync

sleek cobalt Feb 7, 2024, 8:44 PM

#

playerId here should come from the Authentication SDK and should be different on the two instances you are using

outer flume Feb 7, 2024, 8:45 PM

#

sleek cobalt playerId here should come from the Authentication SDK and should be different on...

I'm adding a debug log to convalidate it

#

Ok this player ID is indeed identical from the two instancies, but the accounts that sign in is different, is the playerID something not related to which player has logged in?

unkempt garnet Feb 7, 2024, 8:50 PM

#

Something weird happening here. Is this still with parrelsync or across PCs?

outer flume Feb 7, 2024, 8:50 PM

#

unkempt garnet Something weird happening here. Is this still with parrelsync or across PCs?

Still Parallelsync

#

I'm on multi monitor

sleek cobalt Feb 7, 2024, 8:56 PM

#

We're looking into it

unkempt garnet Feb 7, 2024, 9:20 PM

#

Okay I was under the impression that profiles were only required when using Anonymous sign in but it seems required for any type of authentication when running on the same machine.

#

So you'll need to either use SetProfile in your InitializationOptions or AuthenticationService.Instance.SwitchProfile before signing in.

#

With parrelsync, you can put an argument to detect that easily

#

and set a profile for that instance of the editor

#

The player id uses the same playerprefs caching system which is shared by default on the same computer

#

Something like

#if UNITY_EDITOR
if (ParrelSync.ClonesManager.IsClone())
{
profile = ParrelSync.ClonesManager.GetArgument();
}
#endif

outer flume Feb 7, 2024, 10:13 PM

#

unkempt garnet Something like #if UNITY_EDITOR if (ParrelSync.ClonesManager.IsClo...

Or i can simple set another profile if it is a clone, instead of Getting the arguments

#

In this case that i have a simple 1v1

unkempt garnet Feb 7, 2024, 10:13 PM

#

If you only intend on having 2 players, sure

outer flume Feb 7, 2024, 10:20 PM

#

TOP! everything is working now, even the "HttpException: (404) HTTP/1.1 404 Not Found" is gone now

#

i think i learn a lot of important lesson of the possible errors when testing these services

#

They can be a little tricky to understand at the beginning

#

I also think that in some way there should be a documentation about these things

#

They are indeed very specific cases but most of the time this is the pipeline for developing a multiplayer game, soo i would consider doing something for these cases in term of docs
