Unreal Engine Pixel Streaming Matchmaker Server Not Working

I am trying to create a multiplayer experience using several Signalling Webservers hosted on different ports on the same instance/ machine but the Matchmaker is not working right in forwarding clients to unoccupied Signalling Servers.

I have created a pixel streaming application now I want to make it so that multiple stacks can be used on a single instance to connect each client to their specific game instance and enable multiplayer and I am using matchmaker for this so whenever a client goes to localhost he get’s automatically forwarded to localhost:70 or 80 depending on occupancy

But when I start matchmaker and then 2 signalling servers with following configuration, and I go to localhost:90, it is saying “All 2 Cirrus servers are in use. Retrying in … seconds.”

Moreover, I have set MatchmakerAddress in Signalling Server config.json as “localhost” so it should forward me from there but that too doesn’t work.

This is Matchmaker config.json

{
	"HttpPort": 90,
	"UseHTTPS": false,
	"MatchmakerPort": 9999,
	"LogToFile": true
}

This is Signalling Server 1 config.json

{
	"UseFrontend": false,
	"UseMatchmaker": true,
	"UseHTTPS": false,
	"UseAuthentication": false,
	"LogToFile": true,
	"LogVerbose": true,
	"HomepageFile": "player.html",
	"AdditionalRoutes": {},
	"EnableWebserver": true,
	"MatchmakerAddress": "localhost",
	"MatchmakerPort": 9999,
	"PublicIp": "localhost",
	"HttpPort": 80,
	"HttpsPort": 443,
	"StreamerPort": 8888,
	"SFUPort": 8889
}

And this is Signalling server 2 config.json

{
	"UseFrontend": false,
	"UseMatchmaker": true,
	"UseHTTPS": false,
	"UseAuthentication": false,
	"LogToFile": true,
	"LogVerbose": true,
	"HomepageFile": "player.html",
	"AdditionalRoutes": {},
	"EnableWebserver": true,
	"MatchmakerAddress": "localhost",
	"MatchmakerPort": 9999,
	"PublicIp": "localhost",
	"HttpPort": 70,
	"HttpsPort": 443,
	"StreamerPort": 8887,
	"SFUPort": 8885
}

Signalling Server log:

Same is for SS2

the WARNING is when I go to localhost:90 (Matchmaker Port) and ping is when I go to individual port of Signalling Web Server i.e. localhost:80

Moreover this is the webpage of localhost:90

There are no errors and manually visiting the Signalling WebServers work but Matchmaking not. I have already spent 2 days trying to figure this out please help me if you can! I would be very grateful

Your second Signalling Server does not seem to be connected to the Matchmaker server, otherwise on the Matchmaker log you will see another set of this log:

12:47:16.927 Message TYPE: connect
12:47:16.927 Adding connection for localhost with playerConnected: false

You mentioned "Same is for SS2", check there again if it says that the SS2 is really connected to the Matchmaker server.

Don't forget to also start 2 instances of the UE application, each with -PixelStreamingPort=8888 and the other one with -PixelStreamingPort=8887.
